NIFI-5096: Periodically poll ZooKeeper to determine the leader for each
registered role in Leader Election. This avoids a condition whereby a node may
occasionally fail to receive notification that it is no longer the elected
leader.
NIFI-5096: More proactively setting leadership to false when ZooKeeper/Curator
ConnectionState changes
This closes #2646
