Harshavardhana dd68cdd802 Auto-reconnect for regular authRPC client. (#3506)
Implement a storage rpc specific rpc client,
which does not reconnect unnecessarily.

Instead reconnect is handled at a different
layer for storage alone.

Rest of the calls using AuthRPC automatically
reconnect, i.e upon an error equal to `rpc.ErrShutdown`
they dial again and call the requested method again.

Harshavardhana d056f19d07 api: Allow reconnection of policy/notification rpc clients. (#3368)
Since we moved out reconnection logic from net-rpc-client.go
we should do it from the top-layer properly and bring back
the code to reconnect properly in-case the connection is lost.

* Remove duplicate MD5 hasher functions.
* Rename listObjectsValidateArgs() into validateListObjectsArgs()
* Remove repeated auth check code in all bucket request handlers.
* Remove abbreviated names in bucket-metadata
* Avoid nested if in bucketPolicyMatchStatement()

Harshavardhana 2f7fb78692 rpc: Our rpcClient should make an attempt to reconnect. (#3221)
rpcClient should attempt a reconnect if the call fails
with 'rpc.ErrShutdown' this is needed since at times when
the servers are taken down and brought back up.

The hijacked connection from net.Dial is usually closed.

So upon first attempt rpcClient might falsely indicate that
disk to be down, to avoid this state make another dial attempt
to really fail.

Fixes #3206
Fixes #3205

Aditya Manthramurthy 85a5c358d8 Add bucket metadata state client/handler (Fixes #3022) (#3152)
- Adds an interface to update in-memory bucket metadata state called
  BucketMetaState - this interface has functions to:
     - update bucket notification configuration,
     - bucket listener configuration,
     - bucket policy configuration, and
     - send bucket event

- This interface is implemented by `localBMS` a type for manipulating
  local node in-memory bucket metadata, and by `remoteBMS` a type for
  manipulating remote node in-memory bucket metadata.

- The remote node interface, makes an RPC call, but the local node
  interface does not - it updates in-memory bucket state directly.

- Rename mkPeersFromEndpoints to makeS3Peers and refactored it.

- Use arrayslice instead of map in s3Peers struct

- `s3Peers.SendUpdate` now receives an arrayslice of peer indexes to
  send the request to, with a special nil value slice indicating that
  all peers should be sent the update.

- `s3Peers.SendUpdate` now returns an arrayslice of errors, representing
  errors from peers when sending an update. The array positions
  correspond to peer array s3Peers.peers

Improve globalS3Peers:

- Make isDistXL a global `globalIsDistXL` and remove from s3Peers

- Make globalS3Peers an array of (address, bucket-meta-state) pairs.

- Fix code and tests.
