support proxying of tagging requests in active-active replication
Note: even if proxying is successful, PutObjectTagging/DeleteObjectTagging
will continue to report a 404 since the object is not present locally.
This PR also increases per node bpool memory from 1024 entries
to 2048 entries; along with that, it also moves the byte pool
centrally instead of being per pool.
Optionally allows customers to enable
- Enable an external cache to catch GET/HEAD responses
- Enable skipping disks that are slow to respond in GET/HEAD
when we have already achieved a quorum
globalDeploymentID was being read while it was being set.
Fixes race:

Several callers to putObjectTar may be fighting to set sc. Move the write out of the loop.
Use static resp, and request elements.
Fixes tests with -race:

- remove targetClient for passing around via replicationObjectInfo{}
- remove cloing to object info unnecessarily
- remove objectInfo from replicationObjectInfo{} (only require necessary fields)
given a versionId the mtime is always the same, it
can never be different than its original value.
versionIds also do not conflict, since they are uuid's
and unique practically forever.
ignoring valid objects with valid replication metadata
after the Prefix was disabled must still honor the older
metadata.
this can lead to unexpected results, allow it during
READ phase always.
Simplify MRF queueing and add backlog handler
- Limit re-tries to 3 to avoid repeated re-queueing. Fall offs
to be re-tried when the scanner revisits this object or upon access.
- Change MRF to have each node process only its MRF entries.
- Collect MRF backlog by the node to allow for current backlog visibility
Optimize DeleteObject API to avoid extra
GetObjectInfo call on the replicating side.
For receiving side, it is just a regular
DeleteObject call.
Bonus: Fix a corner case where version purged is
absent on target (either due to replication not yet
complete or target version already deleted in a
one-way replication or when replication was disabled).
In such cases, mark version purge complete.
* Reduce allocations
* Add stringsHasPrefixFold which can compare string prefixes, while ignoring case and not allocating.
* Reuse all msgp.Readers
* Reuse metadata buffers when not reading data.
* Make type safe. Make buffer 4K instead of 8.
* Unslice
- lifecycle must return InvalidArgument for rule errors
- do not return `null` versionId in HTTP header
- reject mixed SSE uploads with correct error message
- getObjectTagging to be allowed for anonymous policies
- return correct errors for invalid retention period
- return sorted list of tags for an object
- putObjectTagging must return 200 OK not 204 OK
- return 409 ErrObjectLockConfigurationNotAllowed for existing buckets
