Description

This is a feature similar to the batch feature in trunk.

We have optimisation for the put path where we batch puts by the regionserver, but for gets and deletes we do batching only per hregion. So, if there are 20 regions on a regionserver, we would be doing 20 RPC when we can potentially batch them together in 1 call.
