> Since HBASE-10566, we have an explicit call timeout available in the client.
> We could forward it to the server, and use this information for:
> - if the call is still in the queue, just cancel it
> - if the call is under execution, makes this information available in RpcCallContext
(actually change the RpcCallContext#disconnectSince to something more generic), so it can
be used by the query under execution to stop its execution
> - in the future, interrupt it to manage the case 'stuck on a dead datanode' or something
similar
> - if the operation has finished, don't send the reply to the client, as by definition
the client is not interested anymore.
> From this, it will be easy to manage the cancellation: disconnect/timeout/cancellation
are similar from a service execution PoV
