fix: avoid races in NewMultipartUpload under multiple pools (#12233)
It is possible in some scenarios that in multiple pools,
two concurrent calls for the same object as a multipart operation
can lead to duplicate entries on two different pools.

This PR fixes this

- hold locks to serialize multiple callers so that we don't race.
- make sure to look for existing objects on the namespace as well
  not just for existing uploadIDs

fix: cleanup locking, cancel context upon lock timeout (#12183)
upon errors to acquire lock context would still leak,
since the cancel would never be called. since the lock

lock: Always cancel the returned Get(R)Lock context (#12162)
* lock: Always cancel the returned Get(R)Lock context

There is a leak with cancel created inside the locking mechanism. The
cancel purpose was to cancel operations such erasure get/put that are
holding non-refreshable locks.

This PR will ensure the created context.Cancel is passed to the unlock
API so it will cleanup and avoid leaks.

* locks: Avoid returning nil cancel in local lockers

Since there is no Refresh mechanism in the local locking mechanism, we
do not generate a new context or cancel. Currently, a nil cancel
function is returned but this can cause a crash. Return a dummy function
instead.

c829e3a13b Support for remote tier management (#12090)
With this change, MinIO's ILM supports transitioning objects to a remote tier.
This change includes support for Azure Blob Storage, AWS S3 compatible object
storage incl. MinIO and Google Cloud Storage as remote tier storage backends.

Some new additions include:

 - Admin APIs remote tier configuration management

 - Simple journal to track remote objects to be 'collected'
   This is used by object API handlers which 'mutate' object versions by
   overwriting/replacing content (Put/CopyObject) or removing the version
   itself (e.g DeleteObjectVersion).

 - Rework of previous ILM transition to fit the new model
   In the new model, a storage class (a.k.a remote tier) is defined by the
   'remote' object storage type (one of s3, azure, GCS), bucket name and a
   prefix.

* Fixed bugs, review comments, and more unit-tests

- Leverage inline small object feature
- Migrate legacy objects to the latest object format before transitioning
- Fix restore to particular version if specified
- Extend SharedDataDirCount to handle transitioned and restored objects
- Restore-object should accept version-id for version-suspended bucket (#12091)
- Check if remote tier creds have sufficient permissions
- Bonus minor fixes to existing error messages

api: Introduce metadata update APIs to update only metadata (#11962)
Current implementation heavily relies on readAllFileInfo
but with the advent of xl.meta inlined with data, we cannot
easily avoid reading data when we are only interested is
updating metadata, this leads to invariably write
amplification during metadata updates, repeatedly reading
data when we are only interested in updating metadata.

This PR ensures that we implement a metadata only update
API at storage layer, that handles updates to metadata alone
for any given version - given the version is valid and
present.

This helps reduce the chattiness for following calls..

- PutObjectTags
- DeleteObjectTags
- PutObjectLegalHold
- PutObjectRetention
- ReplicateObject (updates metadata on replication status)

Various improvements in replication (#11949)
- collect real time replication metrics for prometheus.
- add pending_count, failed_count metric for total pending/failed replication operations.

- add API to get replication metrics

- add MRF worker to handle spill-over replication operations

- multiple issues found with replication
- fixes an issue when client sends a bucket
 name with `/` at the end from SetRemoteTarget
 API call make sure to trim the bucket name to 
 avoid any extra `/`.

- hold write locks in GetObjectNInfo during replication
  to ensure that object version stack is not overwritten
  while reading the content.

- add additional protection during WriteMetadata() to
  ensure that we always write a valid FileInfo{} and avoid
  ever writing empty FileInfo{} to the lowest layers.

avoid healObjects recursively healing at empty path (#11856)
baseDirFromPrefix(prefix) for object names without
parent directory incorrectly uses empty path, leading
to long listing at various paths that are not useful
for healing - avoid this listing completely if "baseDir"
returns empty simple use the "prefix" as is.

this improves startup performance significantly

remove GetObject from ObjectLayer interface (#11635)
This commit removes the `GetObject` method
from the `ObjectLayer` interface.

The `GetObject` method is not longer used by
the HTTP handlers implementing the high-level
S3 semantics. Instead, they use the `GetObjectNInfo`
method which returns both, an object handle as well
as the object metadata.

Therefore, it is no longer necessary that a concrete
`ObjectLayer` implements `GetObject`.

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

```
aws s3api list-objects --endpoint-url http://localhost:9000 \
    --profile minio --bucket testbucket-v --prefix new/ --delimiter /
{
    "CommonPrefixes": [
        {

        {
