snowball: return errors on failures (#13836)
Return errors when untar fails at once.

Current error handling was quite a mess. Errors are written 
to the stream, but processing continues.

Instead, return errors when they occur and transform 
internal errors to bad request errors, since it is likely a 
problem with the input.

Add new `site` config sub-system intended to replace `region` (#13672)
- New sub-system has "region" and "name" fields.

- `region` subsystem is marked as deprecated, however still works, unless the
new region parameter under `site` is set - in this case, the region subsystem is
ignored. `region` subsystem is hidden from top-level help (i.e. from `mc admin
config set myminio`), but appears when specifically requested (i.e. with `mc
admin config set myminio region`).

- MINIO_REGION, MINIO_REGION_NAME are supported as legacy environment variables for server region.

- Adds MINIO_SITE_REGION as the current environment variable to configure the
server region and MINIO_SITE_NAME for the site name.

re-use io.Copy buffers with 32k pools (#13553)
Borrowed idea from Go's usage of this
optimization for ReadFrom() on client

etag: compute ETag as MD5 for compressed single-part objects (#12375)
This commit fixes a bug causing the MinIO server to compute
the ETag of a single-part object as MD5 of the compressed
content - not as MD5 of the actual content.

This usually does not affect clients since the MinIO appended
a `-1` to indicate that the ETag belongs to a multipart object.
However, this behavior was problematic since:
 - A S3 client being very strict should reject such an ETag since
   the client uploaded the object via single-part API but got
   a multipart ETag that is not the content MD5.
 - The MinIO server leaks (via the ETag) that it compressed the
   object.

This commit addresses both cases. Now, the MinIO server returns
an ETag equal to the content MD5 for single-part objects that got
compressed.

sse: add support for SSE-KMS bucket configurations (#12295)
This commit adds support for SSE-KMS bucket configurations.
Before, the MinIO server did not support SSE-KMS, and therefore,
it was not possible to specify an SSE-KMS bucket config.

Now, this is possible. For example:
```
mc encrypt set sse-kms some-key <alias>/my-bucket
```

Further, this commit fixes an issue caused by not supporting
SSE-KMS bucket configuration and switching to SSE-KMS as default
SSE method.

Before, the server just checked whether an SSE bucket config was
present (not which type of SSE config) and applied the default
SSE method (which was switched from SSE-S3 to SSE-KMS).

This caused objects to get encrypted with SSE-KMS even though a
SSE-S3 bucket config was present.

This issue is fixed as a side-effect of this commit.

Krishnan Parthasarathi 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)

pkg/etag: add new package for S3 ETag handling (#11577)
This commit adds a new package `etag` for dealing
with S3 ETags.

Even though ETag is often viewed as MD5 checksum of
an object, handling S3 ETags correctly is a surprisingly
complex task. While it is true that the ETag corresponds
to the MD5 for the most basic S3 API operations, there are
many exceptions in case of multipart uploads or encryption.

In worse, some S3 clients expect very specific behavior when
it comes to ETags. For example, some clients expect that the
ETag is a double-quoted string and fail otherwise.
Non-AWS compliant ETag handling has been a source of many bugs
in the past.

Therefore, this commit adds a dedicated `etag` package that provides
functionality for parsing, generating and converting S3 ETags.
Further, this commit removes the ETag computation from the `hash`
package. Instead, the `hash` package (i.e. `hash.Reader`) should
focus only on computing and verifying the content-sha256.

One core feature of this commit is to provide a mechanism to
communicate a computed ETag from a low-level `io.Reader` to
a high-level `io.Reader`.

This problem occurs when an S3 server receives a request and
has to compute the ETag of the content. However, the server
may also wrap the initial body with several other `io.Reader`,
e.g. when encrypting or compressing the content:
```
   reader := Encrypt(Compress(ETag(content)))
```
In such a case, the ETag should be accessible by the high-level
`io.Reader`.

The `etag` provides a mechanism to wrap `io.Reader` implementations
such that the `ETag` can be accessed by a type-check.
This technique is applied to the PUT, COPY and Upload handlers.

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)

```

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.

for encryption only if KMS is configured.

Make sure that this predictability is maintained, currently
the code was allowing encryption to go through and fail
at later to indicate that KMS was not configured. We should
simply reply "NotImplemented" if KMS is not configured, this
allows clients to simply proceed with their tests.

delayed locks until we have started reading the body (#10474)
This is to ensure that Go contexts work properly, after some
interesting experiments I found that Go net/http doesn't
cancel the context when Body is non-zero and hasn't been
read till EOF.

The following gist explains this, this can lead to pile up
of go-routines on the server which will never be canceled
and will die at a really later point in time, which can
simply overwhelm the server.

https://gist.github.com/harshavardhana/c51dcfd055780eaeb71db54f9c589150

To avoid this refactor the locking such that we take locks after we
have started reading from the body and only take locks when needed.

Also, remove contextReader as it's not useful, doesn't work as expected
context is not canceled until the body reaches EOF so there is no point
in wrapping it with context and putting a `select {` on it which
can unnecessarily increase the CPU overhead.

We will still use the context to cancel the lockers etc.
Additional simplification in the locker code to avoid timers
as re-using them is a complicated ordeal avoid them in
the hot path, since locking is very common this may avoid
lots of allocations.

fix: CopyObject behavior on expanded zones (#9729)
CopyObject was not correctly figuring out the correct
destination object location and would end up creating
duplicate objects on two different zones, reproduced
by doing encryption based key rotation.

Introduce simpler GetMultipartInfo call for performance (#9722)
Advantages avoids 100's of stats which are needed for each
upload operation in FS/NAS gateway mode when uploading a large
multipart object, dramatically increases performance for
multipart uploads by avoiding recursive calls.

For other gateway's simplifies the approach since
azure, gcs, hdfs gateway's don't capture any specific
metadata during upload which needs handler validation
for encryption/compression.

Erasure coding was already optimized, additionally
just avoids small allocations of large data structure.

fix: reply back user-metadata in lower case form (#9697)
some clients such as veeam expect the x-amz-meta to
be sent in lower cased form, while this does indeed
defeats the HTTP protocol contract it is harder to
change these applications, while these applications
get fixed appropriately in future.

x-amz-meta is usually sent in lowercased form
by AWS S3 and some applications like veeam
incorrectly end up relying on the case sensitivity
of the HTTP headers.

Bonus fixes

 - Fix the iso8601 time format to keep it same as
   AWS S3 response
 - Increase maxObjectList to 50,000 and use
   maxDeleteList as 10,000 whenever multi-object
   deletes are needed.

fix size accounting for encrypted/compressed objects (#9690)
size calculation in crawler was using the real size
of the object instead of its actual size i.e either
a decrypted or uncompressed size.

this is needed to make sure all other accounting
such as bucket quota and mcs UI to display the
correct values.

migrate all bucket metadata into a single file (#9586)
this is a major overhaul by migrating off all
bucket metadata related configs into a single
object '.metadata.bin' this allows us for faster
bootups across 1000's of buckets and as well
as keeps the code simple enough for future
work and additions.

Additionally also fixes #9396, #9394
