Add a node in ZK to tell all masters to shutdown.

Key: HBASE-1448
URL: https://issues.apache.org/jira/browse/HBASE-1448
Project: Hadoop HBase
Issue Type: New Feature
Reporter: Jean-Daniel Cryans
Assignee: Jean-Daniel Cryans
Priority: Critical
Fix For: 0.20.0
Currently, shutting down a multi-master HBase is a bit of a mess since the
backup masters aren't pinged by the stop-hbase script. To shut them down, you
have to do a hbase-daemons.sh stop master. Also, with master failover in place,
the backup masters may try to come alive. This can be solved by adding a
"shutdown node" in ZK on which all masters should be listening.
