> It is an enhancement for HDDS-3188.
> Like OMFailoverProxyProvider, SCMBlockLocationFailoverProxyProvider should
> also handle LeaderNotReadyException.
> If SCM client (like OzoneManager) has touched leader SCM, meanwhile leader
> SCM is stuck in replaying raft log entries(e.g., that SCM restarts and
> becomes leader, it needs time to recover its state machine by replaying all
> raft log entries), SCM client should not round robin to the next SCM, It
> should wait and retry the same SCM later.
