etag: add Format and Decrypt functions (#14659)
This commit adds two new functions to the
internal `etag` package:
 - `ETag.Format`
 - `Decrypt`

The `Decrypt` function decrypts an encrypted
ETag using a decryption key. It returns not
encrypted / multipart ETags unmodified.

The `Decrypt` function is mainly used when
handling SSE-S3 encrypted single-part objects.
In particular, the ETag of an SSE-S3 encrypted
single-part object needs to be decrypted since
S3 clients expect that this ETag is equal to the
content MD5.

The `ETag.Format` method also covers SSE ETag handling.
MinIO encrypts all ETags of SSE single part objects.
However, only the ETag of SSE-S3 encrypted single part
objects needs to be decrypted.
The ETag of an SSE-C or SSE-KMS single part object
does not correspond to its content MD5 and can be
a random value.
The `ETag.Format` function formats an ETag such that
it is an AWS S3 compliant ETag. In particular, it
returns non-encrypted ETags (single / multipart)
unmodified. However, for encrypted ETags it returns
the trailing 16 bytes as ETag. For encrypted ETags
the last 16 bytes will be a random value.

The main purpose of `Format` is to format ETags
such that clients accept them as well-formed AWS S3
ETags.
It differs from the `String` method since `String`
will return string representations for encrypted
ETags that are not AWS S3 compliant.

Write deployment id to health report at the start (#14673)
The deployment id was being written to the health report towards the end
of the handler. Because of this, if there was a timeout in any of the
data fetching, the deployment id was not getting written at all. Upload
of such reports fails on SUBNET as deployment id is the unique
identifier for a cluster in subnet.

Fixed by writing the deployment id at the beginning of the processing.

ListObjectParts: simplify ETag decryption and size adjustment (#14653)
This commit simplifies the ETag decryption and size adjustment
when listing object parts.

When listing object parts, MinIO has to decrypt the ETag of all
parts if and only if the object resp. the parts is encrypted using
SSE-S3.
In case of SSE-KMS and SSE-C, MinIO returns a pseudo-random ETag.
This is inline with AWS S3 behavior.

Further, MinIO has to adjust the size of all encrypted parts due to
the encryption overhead.

The ListObjectParts does specifically not use the KMS bulk decryption
API (4d2fc530d0) since the ETags of all
parts are encrypted using the same object encryption key. Therefore,
MinIO only has to connect to the KMS once, even if there are multiple
parts resp. ETags. It can simply reuse the same object encryption key.

kes: add support for encrypted private keys (#14650)
This commit adds support for encrypted KES
client private keys.

Now, it is possible to encrypt the KES client
private key (`MINIO_KMS_KES_KEY_FILE`) with
a password.

For example, KES CLI already supports the
creation of encrypted private keys:
```
kes identity new --encrypt --key client.key --cert client.crt MinIO
```

To decrypt an encrypted private key, the password
needs to be provided:
```
MINIO_KMS_KES_KEY_PASSWORD=<password>
```

listing: decrypt only SSE-S3 single-part ETags (#14638)
This commit optimises the ETag decryption when
listing objects.

When MinIO lists objects, it has to decrypt the
ETags of single-part SSE-S3 objects.

It does not need to decrypt ETags of
 - plaintext objects => Their ETag is not encrypted
 - SSE-C objects     => Their ETag is not the content MD5
 - SSE-KMS objects   => Their ETag is not the content MD5
 - multipart objects => Their ETag is not encrypted

Hence, MinIO only needs to make a call to the KMS
when it needs to decrypt a single-part SSE-S3 object.
It can resolve the ETags off all other object types
locally.

This commit implements the above semantics by
processing an object listing in batches.
If the batch contains no single-part SSE-S3 object,
then no KMS calls will be made.

If the batch contains at least one single-part
SSE-S3 object we have to make at least one KMS call.
No we first filter all single-part SSE-S3 objects
such that we only request the decryption keys for
these objects.
Once we know which objects resp. ETags require a
decryption key, MinIO either uses the KES bulk
decryption API (if supported) or decrypts each
ETag serially.

This commit is a significant improvement compared
to the previous listing code. Before, a single
non-SSE-S3 object caused MinIO to fall-back to
a serial ETag decryption.
For example, if a batch consisted of 249 SSE-S3
objects and one single SSE-KMS object, MinIO would
send 249 requests to the KMS.
Now, MinIO will send a single request for exactly
those 249 objects and skip the one SSE-KMS object
since it can handle its ETag locally.

Further, MinIO would request decryption keys
for SSE-S3 multipart objects in the past - even
though multipart ETags are not encrypted.
So, if a bucket contained only multipart SSE-S3
objects, MinIO would make totally unnecessary
requests to the KMS.
Now, MinIO simply skips these multipart objects
since it can handle the ETags locally.

Always get the actual object size (#14637)
In bulk ETag decryption, do not rely on the etag to check if it is
encrypted or not to decide if we should set the actual object size in
ObjectInfo. The reason is that multipart objects ETags are not
encrypted.

Always get the actual object size in that case.

add support for SSE-S3 bulk ETag decryption (#14627)
This commit adds support for bulk ETag
decryption for SSE-S3 encrypted objects.

If KES supports a bulk decryption API, then
MinIO will check whether its policy grants
access to this API. If so, MinIO will use
a bulk API call instead of sending encrypted
ETags serially to KES.

Note that MinIO will not use the KES bulk API
if its client certificate is an admin identity.

MinIO will process object listings in batches.
A batch has a configurable size that can be set
via `MINIO_KMS_KES_BULK_API_BATCH_SIZE=N`.
It defaults to `500`.

This env. variable is experimental and may be
renamed / removed in the future.

PutObjectPart: set SSE-KMS headers and truncate ETags. (#14578)
This commit fixes two bugs in the `PutObjectPartHandler`.
First, `PutObjectPart` should return SSE-KMS headers
when the object is encrypted using SSE-KMS.
Before, this was not the case.

Second, the ETag should always be a 16 byte hex string,
perhaps followed by a `-X` (where `X` is the number of parts).
However, `PutObjectPart` used to return the encrypted ETag
in case of SSE-KMS. This leaks MinIO internal etag details
through the S3 API.

The combination of both bugs causes clients that use SSE-KMS
to fail when trying to validate the ETag. Since `PutObjectPart`
did not send the SSE-KMS response headers, the response looked
like a plaintext `PutObjectPart` response. Hence, the client
tries to verify that the ETag is the content-md5 of the part.
This could never be the case, since MinIO used to return the
encrypted ETag.

Therefore, clients behaving as specified by the S3 protocol
tried to verify the ETag in a situation they should not.

Add local disk health checks (#14447)
The main goal of this PR is to solve the situation where disks stop 
responding to operations. This generally causes an FD build-up and 
eventually will crash the server.

This adds detection of hung disks, where calls on disk get stuck.

We add functionality to `xlStorageDiskIDCheck` where it keeps 
track of the number of concurrent requests on a given disk.

A total number of 100 operations are allowed. If this limit is reached 
we will block (but not reject) new requests, but we will monitor the 
state of the disk.

If no requests have been completed or updated within a 15-second 
window, we mark the disk as offline. Requests that are blocked will be 
unblocked and return an error as "faulty disk".

New requests will be rejected until the disk is marked OK again.

Once a disk has been marked faulty, a check will run every 5 seconds that 
will attempt to write and read back a file. As long as this fails the disk will 
remain faulty.

To prevent lots of long-running requests to mark the disk faulty we 
implement a callback feature that allows updating the status as parts 
of these operations are running.

We add a reader and writer wrapper that will update the status of each 
successful read/write operation. This should allow fine enough granularity 
that a slow, but still operational disk will not reach 15 seconds where 
50 operations have not progressed.

Note that errors themselves are not enough to mark a disk faulty. 
A nil (or io.EOF) error will mark a disk as "good".

* Make concurrent disk setting configurable via `_MINIO_DISK_MAX_CONCURRENT`.

* de-couple IsOnline() from disk health tracker

The purpose of IsOnline() is to ensure that we
reconnect the drive only when the "drive" was

- disconnected from network we need to validate
  if the drive is "correct" and is the same drive
  which belongs to this server.

- drive was replaced we have to format it - we
  support hot swapping of the drives.

IsOnline() is not meant for taking the drive offline
when it is hung, it is not useful we can let the
drive be online instead "return" errors for relevant
calls.

* return errFaultyDisk for DiskInfo() call

Co-authored-by: Harshavardhana <harsha@minio.io>

Possible future Improvements:

* Unify the REST server and local xlStorageDiskIDCheck. This would also improve stats significantly.
* Allow reads/writes to be aborted by the context.
* Add usage stats, concurrent count, blocked operations, etc.

kes: remove unnecessary error conversion (#14459)
This commit removes some duplicate code that
converts KES API errors.

This code was added since KES `0.18.0` changed
some exported API errors. However, the KES SDK
handles this error conversion itself.
Therefore, it is not necessary to duplicate this
behavior in MinIO.

See: 21555fa624/error.go (L94)

A potential side affect of this is closing perfectly online

DeleteMarkers do not have a default quorum, i.e it is possible that
DeleteMarkers were created with n/2+1 quorum as well to make sure
that we satisfy situations such as those we need to make sure delete
markers only expect n/2 read quorum.

Additionally we should also look at additional metadata on the
actual objects that might have been "erasure" upgraded with new
parity when disks are down.

In such a scenario do not default to the standard storage class
parity, instead use the parityBlocks present on the FileInfo to
ensure that we are dealing with the correct quorum for READs and
DELETEs.

cached diskIDs are not needed for scanner healing (#14170)
This PR removes an unnecessary state that gets
passed around for DiskIDs, which is not necessary
since each disk exactly knows which pool and which
set it belongs to on a running system.

Currently cached DiskId's won't work properly
because it always ends up skipping offline disks
and never runs healing when disks are offline, as
it expects all the cached diskIDs to be present
always. This also sort of made things in-flexible
in terms perhaps a new diskID for `format.json`.
(however this is not a big issue)

This is an unnecessary requirement that healing
via scanner needs all drives to be online, instead
healing should trigger even when partial nodes
and drives are available this ensures that we
keep the SLA in-tact on the objects when disks
are offline for a prolonged period of time.

Fix inconsistent metadata after healing (#14125)
When calculating signatures empty part ETags were not discarded, leading 
to a different signature compared to freshly created ones.

This would mean that after a heal signature of the healed metadata would be 
different. Fixing the calculation of signature will make these consistent.

Furthermore when inconsistent entries, with zero version ID, with the same 
mod times but different signatures, the one with the lowest signature would 
be picked for quorum check. Since this is 50/50, we fall back to a simple 
quorum count on all signatures.

Each of these fixes by themselves will lead to quorum. Tests were added 
for regressions and expected outcomes.

heal: isObjectDangling should return false when it cannot decide (#14053)
In a multi-pool setup when disks are coming up, or in a single pool
setup let's say with 100's of erasure sets with a slow network.

It's possible when healing is attempted on `.minio.sys/config`
folder, it can lead to healing unexpectedly deleting some policy
files as dangling due to a mistake in understanding when `isObjectDangling`
is considered to be 'true'.

This issue happened in commit 30135eed86
when we assumed the validMeta with empty ErasureInfo is considered
to be fully dangling. This implementation issue gets exposed when
the server is starting up.

This is most easily seen with multiple-pool setups because of the
disconnected fashion pools that come up. The decision to purge the
object as dangling is taken incorrectly prior to the correct state
being achieved on each pool, when the corresponding drive let's say
returns 'errDiskNotFound', a 'delete' is triggered. At this point,
the 'drive' comes online because this is part of the startup sequence
as drives can come online lazily.

This kind of situation exists because we allow (totalDisks/2) number
of drives to be online when the server is being restarted.

Implementation made an incorrect assumption here leading to policies
getting deleted.

Added tests to capture the implementation requirements.
