verify RenameData() versions to be consistent (#15649)
xl.meta gets written and never rolled back, however
we definitely need to validate the state that is
persisted on the disk, if there are inconsistencies

- more than write quorum we should return an error
  to the client

- if write quorum was achieved however there are
  inconsistent xl.meta's we should simply trigger
  an MRF on them

Independent Multipart Uploads (#15346)
Do completely independent multipart uploads.

In distributed mode, a lock was held to merge each multipart 
upload as it was added. This lock was highly contested and 
retries are expensive (timewise) in distributed mode.

Instead, each part adds its metadata information uniquely. 
This eliminates the per object lock required for each to merge.
The metadata is read back and merged by "CompleteMultipartUpload" 
without locks when constructing final object.

fix: for DiskInfo call cache disk metrics (#15229)
Small uploads spend a significant amount of time (~5%) fetching disk info metrics. Also maps are allocated for each call.

Add a 100ms cache to disk metrics.

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.

remove double reads delete versions (#13544)
deleting collection of versions belonging
to same object, we can avoid re-reading
the xl.meta from the disk instead purge
all the requested versions in-memory,

the tradeoff is to allocate a map to de-dup
the versions, allow disks to be read only
once per object.

additionally reduce the data transfer between
nodes by shortening msgp data values.

Furthermore allow `inspect` to do direct decode from `mc`, for example:

```
λ mc admin inspect --json local2/testbucket/nyc-taxi-data-10M.csv.zst/*|inspect -json
Output decrypted to inspect.5f0643b2.zip
```

- Correct error, forward non-EOF errors.
- Add some extra safety. Log FNF when no files.
- Add `xl-meta` zip support.
For `xl-meta` multiple inputs output object with names as key.
Automatically switches `xl-meta` to single-line output when multiple objects.
Add double-star wildcard support to xl-meta input.

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)

fix: readData in bulk call using messagepack byte wrappers (#11228)
This PR refactors the way we use buffers for O_DIRECT and
to re-use those buffers for messagepack reader writer.

After some extensive benchmarking found that not all objects
have this benefit, and only objects smaller than 64KiB see
this benefit overall.

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.

Reduce WriteAll allocs (#10810)
WriteAll saw 127GB allocs in a 5 minute timeframe for 4MiB buffers 
used by `io.CopyBuffer` even if they are pooled.

Since all writers appear to write byte buffers, just send those 
instead and write directly. The files are opened through the `os` 
package so they have no special properties anyway.

This removes the alloc and copy for each operation.

REST sends content length so a precise alloc can be made.

ListObjects Metadata Caching (#10648)
Design: https://gist.github.com/klauspost/025c09b48ed4a1293c917cecfabdf21c

Gist of improvements:

* Cross-server caching and listing will use the same data across servers and requests.
* Lists can be arbitrarily resumed at a constant speed.
* Metadata for all files scanned is stored for streaming retrieval.
* The existing bloom filters controlled by the crawler is used for validating caches.
* Concurrent requests for the same data (or parts of it) will not spawn additional walkers.
* Listing a subdirectory of an existing recursive cache will use the cache.
* All listing operations are fully streamable so the number of objects in a bucket no 
  longer dictates the amount of memory.
* Listings can be handled by any server within the cluster.
* Caches are cleaned up when out of date or superseded by a more recent one.

Add storage layer contexts (#10321)
Add context to all (non-trivial) calls to the storage layer. 

Contexts are propagated through the REST client.

- `context.TODO()` is left in place for the places where it needs to be added to the caller.
- `endWalkCh` could probably be removed from the walkers, but no changes so far.

The "dangerous" part is that now a caller disconnecting *will* propagate down,  so a 
"delete" operation will now be interrupted. In some cases we might want to disconnect 
this functionality so the operation completes if it has started, leaving the system in a cleaner state.
