> Add admin command to display leader

> Key: ZOOKEEPER-3385
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3385
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.6.0
> Reporter: Brian Nixon
> Priority: Trivial
> Labels: pull-request-available
>
> 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.
