-----------------------------------------

forgot that this patch depends on HBASE-15106 (that's why it does not apply)

> Adds the "region locking" that will be used to perform assign/unassign, split/merge operations.
> An operation take the xlock on the regions is working on, all the other procedures will
be suspended (removed from the runnable queue) and resumed (put back in the runnable queue)
when the operation that has the lock on the region is completed.
