Support bucket versioning (#9377)
- Implement a new xl.json 2.0.0 format to support,
  this moves the entire marshaling logic to POSIX
  layer, top layer always consumes a common FileInfo
  construct which simplifies the metadata reads.
- Implement list object versions
- Migrate to siphash from crchash for new deployments
  for object placements.

Fixes #2111

fix: avoid timer leaks in dsync/lsync (#9781)
At a customer setup with lots of concurrent calls
it can be observed that in newRetryTimer there
were lots of tiny alloations which are not
relinquished upon retries, in this codepath
we were only interested in re-using the timer
and use it wisely for each locker.

Disable crawler in FS/NAS gateway mode (#9695)
No one really uses FS for large scale accounting
usage, neither we crawl in NAS gateway mode. It is
worthwhile to simply disable this feature as its
not useful for anyone.

Bonus disable bucket quota ops as well in, FS
and gateway mode

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.

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

bootups across 1000's of buckets and as well
as keeps the code simple enough for future
work and additions.

cleanup object-lock/bucket tagging for gateways (#9548)

layer APIs for necessary S3 API level functionalities
allowing gateway implementations to return proper

well.

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 API's for managing bucket quota (#9379)
This PR allows setting a "hard" or "fifo" quota
restriction at the bucket level. Buckets that
have reached the FIFO quota configured, will
automatically be cleaned up in FIFO manner until
bucket usage drops to configured quota.
If a bucket is configured with a "hard" quota
ceiling, all further writes are disallowed.

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.

Add rate limiter for S3 API layer (#9196)
- total number of S3 API calls per server
- maximum wait duration for any S3 API call

This implementation is primarily meant for situations
where HDDs are not capable enough to handle the incoming
workload and there is no way to throttle the client.

This feature allows MinIO server to throttle itself
such that we do not overwhelm the HDDs.

fix: various optimizations, idiomatic changes (#9179)
- acquire since leader lock for all background operations
  - healing, crawling and applying lifecycle policies.

- simplify lifecyle to avoid network calls, which was a
  bug in implementation - we should hold a leader and
  do everything from there, we have access to entire
  name space.

- make listing, walking not interfere by slowing itself
  down like the crawler.

- effectively use global context everywhere to ensure
  proper shutdown, in cache, lifecycle, healing

- don't read `format.json` for prometheus metrics in
  StorageInfo() call.
