> Each QuorumPeer prints the identity of the server it believes is the leader in its logs
but that is not easily turned into diagnostic information about the state of the ensemble.
It can be useful in debugging various issues, both when a quorum is struggling to be established
and when a minority of peers are failing to follow, to see at a glance which peers are following
the leader elected by the majority and which peers are either not following or following a
different server.
> Create an admin command that exposes which server a peer believes is the current leader.
