Log:
Set Sleep Time for Rolling Restarts

Summary:
Default sleep time to 60 sec.  Total of 2 min, one for stop and one for start,
per RS.  Note that I had to change regionservers.sh so bin/start-hbase.sh
doesn't use this wait.  Need to figure out a long term solution with public
branch, but this will allow us to do rolling restart on your tiers now.

Test Plan:
bin/rolling-restart.sh
