Review request for Ted Yu, Michael Stack and ramkrishna vasudevan.
Summary
-------
Under some scenarios, we use the function of disable/enable HTable. But
currently, enable HTable uses the random-assignment. We hope all the regions
show a better distribution, no matter how many regions and how many
regionservers.
So I suggest to add an option of using round-robin assignment on enable-table.
This addresses bug HBASE-4669.
