Review request for hbase.
Changes
-------
- regionservers were being restarted in parallel. need to restart serially
- wait for the master znode to expire before restarting the masters (this is
especially necessary with backup masters)
Summary
-------
1. added 'restart' option to hbase-daemon.sh for unit-level restarting
2. added rolling-restart.sh script to perform system-level rolling restarts
(Note that I intentionally did not restart the ZooKeeper nodes, since those
binaries will need an update far less often)
This addresses bug HBASE-1660.
