fix: reduce crawler memory usage by orders of magnitude (#11556)
currently crawler waits for an entire readdir call to
return until it processes usage, lifecycle, replication
and healing - instead we should pass the applicator all
the way down to avoid building any special stack for all
the contents in a single directory.

This allows for

- no need to remember the entire list of entries per directory
  before applying the required functions
- no need to wait for entire readdir() call to finish before
  applying the required functions

fix: osinfos incomplete in case of warnings (#11505)
The function used for getting host information
(host.SensorsTemperaturesWithContext) returns warnings in some cases.

Returning with error in such cases means we miss out on the other useful
information already fetched (os info).

If the OS info has been succesfully fetched, it should always be
included in the output irrespective of whether the other data (CPU
sensors, users) could be fetched or not.

fix: metacache should only rename entries during cleanup (#11503)
To avoid large delays in metacache cleanup, use rename
instead of recursive delete calls, renames are cheaper
move the content to minioMetaTmpBucket and then cleanup
this folder once in 24hrs instead.

If the new cache can replace an existing one, we should
let it replace since that is currently being saved anyways,
this avoids pile up of 1000's of metacache entires for
same listing calls that are not necessary to be stored
on disk.

Simplify PutObjReader for plain-text reader usage (#11470)
This change moves away from a unified constructor for plaintext and encrypted
usage. NewPutObjReader is simplified for the plain-text reader use. For
encrypted reader use, WithEncryption should be called on an initialized PutObjReader.

Plaintext:
func NewPutObjReader(rawReader *hash.Reader) *PutObjReader

The hash.Reader is used to provide payload size and md5sum to the downstream
consumers. This is different from the previous version in that there is no need
to pass nil values for unused parameters.

Encrypted:
func WithEncryption(encReader *hash.Reader,
key *crypto.ObjectKey) (*PutObjReader, error)

This method sets up encrypted reader along with the key to seal the md5sum
produced by the plain-text reader (already setup when NewPutObjReader was
called).

Usage:
```
  pReader := NewPutObjReader(rawReader)
  // ... other object handler code goes here

  // Prepare the encrypted hashed reader
  pReader, err = pReader.WithEncryption(encReader, objEncKey)

fix: listing for directory object when delimiter is present (#11463)
When you have heirarchy of prefixes with directory objects
our current master would list directory objects as prefixes
when delimiter is present, this is inconsistent with AWS S3

```

    --profile minio --bucket testbucket-v --prefix new/ --delimiter /
{
    "CommonPrefixes": [
        {

crypto: add support for decrypting SSE-KMS metadata (#11415)
This commit refactors the SSE implementation and add
S3-compatible SSE-KMS context handling.

SSE-KMS differs from SSE-S3 in two main aspects:
 1. The client can request a particular key and
    specify a KMS context as part of the request.
 2. The ETag of an SSE-KMS encrypted object is not
    the MD5 sum of the object content.

This commit only focuses on the 1st aspect.

A client can send an optional SSE context when using
SSE-KMS. This context is remembered by the S3 server
such that the client does not have to specify the
context again (during multipart PUT / GET / HEAD ...).
The crypto. context also includes the bucket/object
name to prevent renaming objects at the backend.

Now, AWS S3 behaves as following:
 - If the user does not provide a SSE-KMS context
   it does not store one - resp. does not include
   the SSE-KMS context header in the response (e.g. HEAD).
 - If the user specifies a SSE-KMS context without
   the bucket/object name then AWS stores the exact
   context the client provided but adds the bucket/object
   name internally. The response contains the KMS context
   without the bucket/object name.
 - If the user specifies a SSE-KMS context with
   the bucket/object name then AWS again stores the exact
   context provided by the client. The response contains
   the KMS context with the bucket/object name.

This commit implements this behavior w.r.t. SSE-KMS.
However, as of now, no such object can be created since
the server rejects SSE-KMS encryption requests.

This commit is one stepping stone for SSE-KMS support.

gateway: don't use encrypted ETags for If-Match (#11400)
This commit fixes a bug in the S3 gateway that causes
GET requests to fail when the object is encrypted by the
gateway itself.

The gateway was not able to GET the object since it always
specified a `If-Match` pre-condition checking that the object
ETag matches an expected ETag - even for encrypted ETags.

The problem is that an encrypted ETag will never match the ETag
computed by the backend causing the `If-Match` pre-condition
to fail.

This commit fixes this by not sending an `If-Match` header when
the ETag is encrypted. This is acceptable because:
  1. A gateway-encrypted object consists of two objects at the backend
     and there is no way to provide a concurrency-safe implementation
     of two consecutive S3 GETs in the deployment model of the S3
     gateway.
     Ref: S3 gateways are self-contained and isolated - and there may
          be multiple instances at the same time (no lock across
          instances).
  2. Even if the data object changes (concurrent PUT) while gateway
     A has download the metadata object (but not issued the GET to
     the data object => data race) then we don't return invalid data
     to the client since the decryption (of the currently uploaded data)
     will fail - given the metadata of the previous object.

crypto: deprecate native Hashicorp Vault support (#11352)
This commit deprecates the native Hashicorp Vault
support and removes the legacy Vault documentation.

The native Hashicorp Vault documentation is marked as
outdated and deprecated for over a year now. We give
another 6 months before we start removing Hashicorp Vault
support and show a deprecation warning when a MinIO server
starts with a native Vault configuration.

Add LDAP Lookup-Bind mode (#11318)
This change allows the MinIO server to be configured with a special (read-only)
LDAP account to perform user DN lookups.

The following configuration parameters are added (along with corresponding
environment variables) to LDAP identity configuration (under `identity_ldap`):

- lookup_bind_dn / MINIO_IDENTITY_LDAP_LOOKUP_BIND_DN
- lookup_bind_password / MINIO_IDENTITY_LDAP_LOOKUP_BIND_PASSWORD
- user_dn_search_base_dn / MINIO_IDENTITY_LDAP_USER_DN_SEARCH_BASE_DN
- user_dn_search_filter / MINIO_IDENTITY_LDAP_USER_DN_SEARCH_FILTER

This lookup-bind account is a service account that is used to lookup the user's
DN from their username provided in the STS API. When configured, searching for
the user DN is enabled and configuration of the base DN and filter for search is
required. In this "lookup-bind" mode, the username format is not checked and must
not be specified. This feature is to support Active Directory setups where the
DN cannot be simply derived from the username.

When the lookup-bind is not configured, the old behavior is enabled: the minio
server performs LDAP lookups as the LDAP user making the STS API request and the
username format is checked and configuring it is required.

fix: LoginSTS should be an inline implementation (#11337)
STS tokens can be obtained by using local APIs
once the remote JWT token is presented, current
code was not validating the incoming token in the
first place and was incorrectly making a network
operation using that token.

For the most part this always works without issues,
but under adversarial scenarios it exposes client
to hand-craft a request that can reach internal
services without authentication.

This kind of proxying should be avoided before
validating the incoming token.

Benefits are seen from almost all objects from

1KiB - 32KiB

Beyond this no objects see benefit with bulk call approach
as the latency of bytes sent over the wire v/s streaming
content directly from disk negate each other with no
remarkable benefits.

All other optimizations include reuse of msgp.Reader,
msgp.Writer using sync.Pool's for all internode calls.

fix: use buffers only when necessary for io.Copy() (#11229)
Use separate sync.Pool for writes/reads

Avoid passing buffers for io.CopyBuffer()
if the writer or reader implement io.WriteTo or io.ReadFrom
respectively then its useless for sync.Pool to allocate
buffers on its own since that will be completely ignored
by the io.CopyBuffer Go implementation.

Improve this wherever we see this to be optimal.

This allows us to be more efficient on memory usage.
```
   385  // copyBuffer is the actual implementation of Copy and CopyBuffer.
   386  // if buf is nil, one is allocated.
   387  func copyBuffer(dst Writer, src Reader, buf []byte) (written int64, err error) {
   388  	// If the reader has a WriteTo method, use it to do the copy.
   389  	// Avoids an allocation and a copy.
   390  	if wt, ok := src.(WriterTo); ok {
   391  		return wt.WriteTo(dst)
   392  	}
   393  	// Similarly, if the writer has a ReadFrom method, use it to do the copy.
   394  	if rt, ok := dst.(ReaderFrom); ok {
   395  		return rt.ReadFrom(src)
   396  	}
```

From readahead package
```
// WriteTo writes data to w until there's no more data to write or when an error occurs.
// The return value n is the number of bytes written.
// Any error encountered during the write is also returned.
func (a *reader) WriteTo(w io.Writer) (n int64, err error) {
	if a.err != nil {
		return 0, a.err
	}
	n = 0
	for {
		err = a.fill()
		if err != nil {

		}
		n2, err := w.Write(a.cur.buffer())
		a.cur.inc(n2)
		n += int64(n2)

Rewrite parentIsObject() function. Currently if a client uploads

The new code will check with the reverse order and quickly quit if

So if a, b, c in 'a/b/c' does not exist in the first place, then returns

- Double healing when bitrot is enabled, instead heal attempt

- If applyActions() is successful and getSize() returns proper
  value, then object is accounted for and should be removed
  from the oldCache namespace map to avoid double heal attempts.

main reason is that HealObjects starts a recursive listing
for each object, this can be a really really long time on

perform HealObject() instead at the prefix.

delete's already handle purging dangling content, we
don't need to achieve this by doing recursive listing,
this in-turn can delay crawling significantly.

Optimizations include

- do not write the metacache block if the size of the

  is attempted for a transient prefix, this helps to
  avoid creating lots of empty metacache entries for
  `minioMetaBucket`

- avoid the entire initialization sequence of cacheCh
  , metacacheBlockWriter if we are simply going to skip
  them when discardResults is set to true.

- No need to hold write locks while writing metacache
  blocks - each block is unique, per bucket, per prefix
  and also is written by a single node.

fix: delimiter based listing was broken without marker (#11136)
with missing nextMarker with delimiter based listing,
top level prefixes beyond 4500 or max-keys value
wouldn't be sent back for client to ask for the next
batch.

reproduced at a customer deployment, create prefixes
as shown below

```
for year in $(seq 2017 2020)
do
    for month in {01..12}
    do for day in {01..31}
       do
           mc -q cp file myminio/testbucket/dir/day_id=$year-$month-$day/;
       done
    done
done
```

Then perform

```
aws s3api --profile minio --endpoint-url http://localhost:9000 list-objects \
    --bucket testbucket --prefix dir/ --delimiter / --max-keys 1000
```

You shall see missing NextMarker, this would disallow listing beyond max-keys
requested and also disallow beyond 4500 (maxKeyObjectList) prefixes being listed
because client wouldn't know the NextMarker available.

This PR addresses this situation properly by making the implementation
more spec compatible. i.e NextMarker in-fact can be either an object, a prefix
with delimiter depending on the input operation.

This issue was introduced after the list caching changes and has been present
for a while.

metacache: Speed up cleanup operation (#11078)
Perform cleanup operations on copied data. Avoids read locking
data while determining which caches to keep.

Also, reduce the log(N*N) operation to log(N*M) where M caches 
with the same root or below when checking potential replacements.

fix: refactor locks to apply them uniquely per node (#11052)
This refactor is done for few reasons below

- to avoid deadlocks in scenarios when number
  of nodes are smaller < actual erasure stripe
  count where in N participating local lockers
  can lead to deadlocks across systems.

- avoids expiry routines to run 1000 of separate
  network operations and routes per disk where
  as each of them are still accessing one single
  local entity.

- it is ideal to have since globalLockServer
  per instance.

- In a 32node deployment however, each server
  group is still concentrated towards the
  same set of lockers that partipicate during
  the write/read phase, unlike previous minio/dsync
  implementation - this potentially avoids send
  32 requests instead we will still send at max
  requests of unique nodes participating in a
  write/read phase.

- reduces overall chattiness on smaller setups.

listcache: Add path index (#11063)
Add a root path index.

```
Before:
Benchmark_bucketMetacache_findCache-32    	   10000	    730737 ns/op

With excluded prints:
Benchmark_bucketMetacache_findCache-32    	   10000	    207100 ns/op

With the root path:
Benchmark_bucketMetacache_findCache-32    	  705765	      1943 ns/op
```

Benchmark used (not linear):

```Go
func Benchmark_bucketMetacache_findCache(b *testing.B) {
	bm := newBucketMetacache("", false)
	for i := 0; i < b.N; i++ {
		bm.findCache(listPathOptions{

reject mixed drive situations with drives on root disks (#11057)
till now we used to match the inode number of the root
drive and the drive path minio would use, if they match
we knew that its a root disk.

this may not be true in all situations such as running
inside a container environment where the container might
be mounted from a different partition altogether, root
disk detection might fail.

fix: etcd import paths again depend on v3.4.14 release (#11020)
Due to botched upstream renames of project repositories
and incomplete migration to go.mod support, our current
dependency version of `go.mod` had bugs i.e it was
using commits from master branch which didn't have
the required fixes present in release-3.4 branches

which leads to some rare bugs

https://github.com/etcd-io/etcd/pull/11477 provides
a workaround for now and we should migrate to this.

release-3.5 eventually claims to fix all of this
properly until then we cannot use /v3 import right now

Temporary workaround for msgp skipping (#10960)
Due to https://github.com/philhofer/fwd/issues/20 when skipping a metadata entry that is >2048 bytes and the buffer is full (2048 bytes) the skip will fail with `io.ErrNoProgress`.

Enlarge the buffer so we temporarily make this much more unlikely.

If it still happens we will have to rewrite the skips to reads.

fix: do not return an error for successfully deleted dangling objects (#10938)
dangling objects when removed `mc admin heal -r` or crawler
auto heal would incorrectly return error - this can interfere
with usage calculation as the entry size for this would be
returned as `0`, instead upon success use the resultant
object size to calculate the final size for the object
and avoid reporting this in the log messages

Also do not set ObjectSize in healResultItem to be '-1'
this has an effect on crawler metrics calculating 1 byte
less for objects which seem to be missing their `xl.meta`
