Description

After HBASE-15593, we can use rpc timeout provided by client to prevent wasting time on requests that have been dropped by client. In request-handling path there are some points that are suitable to check if we can finish this request in time.

We can do this work in several sub-tasks to make sure each one is simple and easy to maintain.
