> Distinguishing read and write request counts, on top of HBASE-3507, would benefit load balancer.
> The action for balancing read vs. write load should be different. For read load, region movement should be low (to keep scanner happy). For write load, region movement is allowed.
> Now that we have cheap(er) counters, it should not be too burdensome keeping up the extra count.
