> RATIS-650 tracks the commit indexes of each peer in a RaftGroup - tracking is
> done as metrics on the RAFT group leader.
> This jira however tracks the RaftLog commit index as a metric of the local
> RaftServer. This metric will be reported by all nodes running a raft server
> irrespective of their role (Leader or Follower).
