> 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.
