> 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.
