storage: Implement GetDiskID request in REST server side (#9720)
GetDiskID() in storage rest client does not really issue a REST request
to the remote disk, but returns an in-memory value instead.

However, GetDiskID() should return an error when format.json is not
found or for other similar issues (unmounted disks, etc..)

GetDiskID() is only called when formatting disks and getting storage
informatio, hence this commit should not have a performance degradation.

Prefer local disks when fetching data blocks (#9563)
If the requested server is part of the set this will always read 
from the local disk, even if the disk contains a parity shard. 
In default setup there is a 50% chance that at least 
one shard that otherwise would have been fetched remotely 
will be read locally instead.

It basically trades RPC call overhead for reed-solomon. 
On distributed localhost this seems to be fairly break-even, 
with a very small gain in throughput and latency. 
However on networked servers this should be a bigger

cache disk info to avoid repeated calls (#9682)
This value is requested on every upload when there are multiple zones.

Since this will result in an RPC call to every remote disk this scales 
quite badly in a distributed setup. Load every 1second interval.

2 servers, localhost only. In large distributed setups much bigger 
gains can be expected.

```
Operations: 21743 -> 22454
* Average: +3.28% (+0.0 MiB/s) throughput, +3.28% (+11.9) obj/s

* Slowest: +8.03% (+0.0 MiB/s) throughput, +8.03% (+22.8) obj/s
```

For easy management of this a generic helper has been added.

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.

avoid net/http ErrorLog for consistent logging experience (#9672)
net/http exposes ErrorLog but it is log.Logger
instance not an interface which can be overridden,
because of this reason the logging is interleaved
sometimes with TLS with messages like this on the
server

```
http: TLS handshake error from 139.178.70.188:63760: EOF
```

This is bit problematic for us as we need to have
consistent logging view for allow --json or --quiet
flags.

With this PR we ensure that this format is adhered to.

fix: possiblity of double write lockers on same resource (#9616)
To avoid this issue with refCounter refactor the code
such that

- locker() always increases refCount upon success
- unlocker() always decrements refCount upon success
  (as a special case removes the resource if the
  refCount is zero)

By these two assumptions we are able to see that we
are never granted two write lockers in any situation.

Thanks to @vcabbage for writing a nice reproducer.

tests: Fix one multi-delete test failure in Windows CI (#9602)
There is a disparency of behavior under Linux & Windows about
the returned error when trying to rename a non existant path.

err := os.Rename("/path/does/not/exist", "/tmp/copy")

Linux:
  isSysErrNotDir(err) = false
  os.IsNotExist(err) = true

Windows:
  isSysErrNotDir(err) = true
  os.IsNotExist(err) = true

ENOTDIR in Linux is returned when the destination path
of the rename call contains a file in one of the middle
segments of the path (e.g. /tmp/file/dst, where /tmp/file
is an actual file not a directory)

However, as shown above, Windows has more scenarios when
it returns ENOTDIR. For example, when the source path contains
an inexistant directory in its path.

In that case, we want errFileNotFound returned and not
errFileAccessDenied, so this commit will add a further check to close
the disparency between Windows & Linux.

allow retries for bucket encryption/policy quorum reloads (#9513)
We should allow quorum errors to be send upwards
such that caller can retry while reading bucket
encryption/policy configs when server is starting
up, this allows distributed setups to load the
configuration properly.

Current code didn't facilitate this and would have
never loaded the actual configs during rolling,
server restarts.

add data update tracking using bloom filter (#9208)
By monitoring PUT/DELETE and heal operations it is possible
to track changed paths and keep a bloom filter for this data. 

This can help prioritize paths to scan. The bloom filter can identify
paths that have not changed, and the few collisions will only result
in a marginal extra workload. This can be implemented on either a
bucket+(1 prefix level) with reasonable performance.

The bloom filter is set to have a false positive rate at 1% at 1M 
entries. A bloom table of this size is about ~2500 bytes when serialized.

To not force a full scan of all paths that have changed cycle bloom
filters would need to be kept, so we guarantee that dirty paths have
been scanned within cycle runs. Until cycle bloom filters have been
collected all paths are considered dirty.

avoid unnecessary KMS requests during single-part PUT (#9220)
This commit fixes a performance issue caused
by too many calls to the external KMS - i.e.
for single-part PUT requests.

In general, the issue is caused by a sub-optimal
code structure. In particular, when the server
encrypts an object it requests a new data encryption
key from the KMS. With this key it does some key
derivation and encrypts the object content and
ETag.

However, to behave S3-compatible the MinIO server
has to return the plaintext ETag to the client
in case SSE-S3.
Therefore, the server code used to decrypt the
(previously encrypted) ETag again by requesting
the data encryption key (KMS decrypt API) from
the KMS.

This leads to 2 KMS API calls (1 generate key and
1 decrypt key) per PUT operation - while only
one KMS call is necessary.

This commit fixes this by fetching a data key only
once from the KMS and keeping the derived object
encryption key around (for the lifetime of the request).

This leads to a significant performance improvement
w.r.t. to PUT workloads:
```
Operation: PUT
Operations: 161 -> 239
Duration: 28s -> 29s
* Average: +47.56% (+25.8 MiB/s) throughput, +47.56% (+2.6) obj/s
* Fastest: +55.49% (+34.5 MiB/s) throughput, +55.49% (+3.5) obj/s
* 50% Median: +58.24% (+32.8 MiB/s) throughput, +58.24% (+3.3) obj/s
* Slowest: +1.83% (+0.6 MiB/s) throughput, +1.83% (+0.1) obj/s

fix: remove the sleep from listing operations (#9287)
make rest of the Walk() function more predictable,
it was observed that in nominal deployments even
without much workload the drives are generally
slow for respond for readdir operations, for the
sleepDuration factor of 10 this can cause
unexpected slowness in the Listing calls, while
it is good for all other I/O, it may simply slow
down Listing immensely which is not useful.

delete: Use physical Dir() for proper prefix cleanup in Windows (#9297)
In FS mode under Windows, removing an object will not automatically.
remove parent empty prefixes.

The reason is that path.Dir() was used, however filepath.Dir() is
more appropriate since filepath is physical (meaning it operates
on OS filesystem paths)

This is not caught because failure for Windows CI is not caught.

add object api check in fs-v1 before returning ready (#9285)
fs-v1 in server mode only checks to see if the path exist, so that it
returns ready before it is indeed ready.

This change adds a check to ensure that the global object api is
available too before reporting ready.

fix: support object-remaining-retention-days policy condition (#9259)
This PR also tries to simplify the approach taken in
object-locking implementation by preferential treatment
given towards full validation.

This in-turn has fixed couple of bugs related to
how policy should have been honored when ByPassGovernance
is provided.

Simplifies code a bit, but also duplicates code intentionally
for clarity due to complex nature of object locking
implementation.

- B2 does actually return an MD5 hash for newly uploaded objects
  so we can use it to provide better compatibility with S3 client
  libraries that assume the ETag is the MD5 hash such as boto.
- depends on change in blazer library.
- new behaviour is only enabled if MinIO's --compat mode is active.
- behaviour for multipart uploads is unchanged (works fine as is).
