How about introducing hbase.balancer.maxregions.perround ?

> See HBASE-3420.  Therein, a wonky cluster had 5k regions on one server and < 1k on
others.  Balancer ran and wanted to redistribute 3k+ all in one go.  Madness.
> If a load of rebalancing to be done, should be done somewhat piecemeal.  We need maximum
regions to rebalance at a time upper bound at a minimum.
