Description

In the replication listener (PartitionReplicaListener) where we have the pattern:

raftFut.thenApply(ignored -> result);

we should worry about handling RAFT exceptions, including analyzing whether raftFut result.

Can distinguish following exception types for RAFT:

• RAFT cannot replicate a command for the timeout (TimeoutException). Hence, this exception leads to the replication timeout exception (ReplicationTimeoutException).
• It throws some internal exception (RaftException). This exception should be wrapped of the common replication exception (ReplicationException).
• Finally, RAFT throws java exceptions (NullPointerException, IndexOutOfRangeException e.t.c). Those exceptions shouldn't be touched, is will be through as is.
