> After HBASE-15593, we have a timeout param in header of RPC requests. We can use it in
more scenes.
> A straightforward scene is to drop requests if it has waited so long in RPC queue and
has been dropped by client. Even if we handle this request and send the response back, it
will not be used any more. And client may have sent a retry. In an extreme case, if the server
is slow, all requests may be timeout or queue-full-exception because we should handle previous
requests which have been dropped by client and many resources at server are wasted.
