Duo Zhang updated HBASE-17346:
------------------------------
    Attachment: HBASE-17346.patch

Add coprocesorService methods in RawAsyncTable. And implement an 
AsyncAggregationClient which only has a max method for now.

As we need the RpcController to pass exceptions for asynchronous stub, which 
means we need a customized RpcController implementation when calling the 
methods of coprocessor stub, I removed the coprocessService method which 
returns an RpcChannel.

Batch coprocessorService has not been implemented yet, just put the patch here 
to collect some feedbacks. Will add full support later(maybe in new issues?)

Thanks.
