jwt: Simplify JWT parsing (#8802)
JWT parsing is simplified by using a custom claim
data structure such as MapClaims{}, also writes
a custom Unmarshaller for faster unmarshalling.

- Avoid as much reflections as possible
- Provide the right types for functions as much
  as possible
- Avoid strings.Join, strings.Split to reduce
  allocations, rely on indexes directly.

Harshavardhana e9b2bf00ad Support MinIO to be deployed on more than 32 nodes (#8492)
This PR implements locking from a global entity into
a more localized set level entity, allowing for locks
to be held only on the resources which are writing
to a collection of disks rather than a global level.

In this process this PR also removes the top-level
limit of 32 nodes to an unlimited number of nodes. This
is a precursor change before bring in bucket expansion.

Harshavardhana 4e63e0e372 Return appropriate errors API versions changes across REST APIs (#8480)
This PR adds code to appropriately handle versioning issues
that come up quite constantly across our API changes. Currently
we were also routing our requests wrong which sort of made it
harder to write a consistent error handling code to appropriately
reject or honor requests.

This PR potentially fixes issues

 - old mc is used against new minio release which is incompatible
   returns an appropriate for client action.
 - any older servers talking to each other, report appropriate error
 - incompatible peer servers should report error and reject the calls
   with appropriate error

have upstream bugs fixed regarding http2 behavior

Krishna Srinivas 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.

Harshavardhana 16c648b109 Remove "Connection" close instead reduce MaxConns per host (#7654)
This is necessary to avoid connection build up between servers
unexpectedly for example in a situation where 16 servers are
talking to each other and one server now allows a maximum of

15*4096 = 61440 idle connections

Will be kept in pool. Such a large pool is perhaps inefficient for
many reasons and also affects overall system resources.

This PR also reduces idleConnection timeout from 120 secs to 60 secs.

Anis Elleuch 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.

Anis Elleuch 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.
