Provide synchronous balanceSwitch()
-----------------------------------

                Key: HBASE-4429
                URL: https://issues.apache.org/jira/browse/HBASE-4429
            Project: HBase
         Issue Type: Task
           Reporter: Ted Yu
           Assignee: Ted Yu

Currently balanceSwitch() doesn't guarantee that balancer isn't running upon
return.
During code review of HBASE-4213, we found that synchronous behavior for
turning off balancer is desired.
We can add blockingBalanceSwitch() to HMasterInterface upon whose return
balancer is guaranteed not running.
