Return if paths are empty in DeleteFileBulk (#8085)
This avoids a network call, also fixes an issue
when empty paths are passed the underlying call
fails with "405 Method Not Allowed".

This is reproducible when you are deleting a
non-existent object.

Fixes #8083

54eded2e6f Do not assume all HTTP errors as Network errors (#7983)
In situations such as when client uploading data,
prematurely disconnects from server such as pressing
ctrl-c before uploading all the data. Under this
situation in distributed setup we prematurely
disconnect disks causing a reconnect loop. This has
an adverse affect we end up leaving a lot of files
in temporary location which ideally should have been
cleaned up when Put() prematurely fails.

This is also a regression which got introduced in #7610

000a60f238 xl: Heal empty parts (#7860)
posix.VerifyFile() doesn't know how to check if a file
is corrupted if that file is empty. We do have the part
size in xl.json so we pass it to VerifyFile to return
an error so healing empty parts can work properly.

74e2fe0879 Return "SlowDown" to S3 clients for network related errors (#7610)
Consider errors returned by httpClient.Do() as network errors. This is because
the http clients returns different types of errors and it is hard to catch
all the error types.

39b3e4f9b3 Avoid using io.ReadFull() for WriteAll and CreateFile (#7676)
With these changes we are now able to peak performances
for all Write() operations across disks HDD and NVMe.

Also adds readahead for disk reads, which also increases
performance for reads by 3x.

9c90a28546 Implement bulk delete (#7607)
Bulk delete at storage level in Multiple Delete Objects API

In order to accelerate bulk delete in Multiple Delete objects API,
a new bulk delete is introduced in storage layer, which will accept
a list of objects to delete rather than only one. Consequently,
a new API is also need to be added to Object API.

Optimize listing with leaf check offloaded to posix (#7541)
Other listing optimizations include

- remove double sorting while filtering object entries
- improve error message when upload-id is not in quorum
- use jsoniter for full unmarshal json, instead of gjson
- remove unused code

Lock: Use REST API instead of RPC (#7469)
In distributed mode, use REST API to acquire and manage locks instead
of RPC.

RPC has been completely removed from MinIO source.

Since we are moving from RPC to REST, we cannot use rolling upgrades as the
nodes that have not yet been upgraded cannot talk to the ones that have
been upgraded.

We expect all minio processes on all nodes to be stopped and then the
upgrade process to be completed.

Also force http1.1 for inter-node communication

53011606a5 Show 401 unauthorized msg when nodes are started with different creds (#7433)
Before this commit, nodes wait indefinitely without showing any
indicate error message when a node is started with different access
and secret keys.

This PR will show '401 Unauthorized' in this case.

f9fecf0e76 storage: Increase the timeout of storage REST requests (#7218)
This commit increases storage REST requests to 5 minutes, this includes
the opening TCP connection, and sending/receiving data. This will reduce
clients receiving errors when the server is under high load.

69bd6df464 storage: Implement Close() in REST client (#6826)
Calling /minio/prometheuses/metrics calls xlSets.StorageInfo() which creates a new
storage REST client and closes it. However, currently, closing does nothing
to the underlying opened http client.

This commit introduces a closing behavior by calling CloseIdleConnections
provided by http.Transport upon the initialization of this latter.

f1f23f6f11 Add sync mode for 'xl.json' (#6798)
xl.json is the source of truth for all erasure
coded objects, without which we won't be able to
read the objects properly. This PR enables sync
mode for writing `xl.json` such all writes go hit
the disk and are persistent under situations such
as abrupt power failures on servers running Minio.
