> Two problems.
> First, as RpcCliemtImpl is the default implementation on branch-1, we need to confirm
that the modification on master does not make it slower. I'm not sure but I used a big lock
to protect everything in the new implementation, so it may have bad impact on performance.
> Second, some configurations of the old AsyncRpcClient is gone. Such as "hbase.rpc.client.threads.max"
and "hbase.rpc.client.nativetransport". Now You could pass a EventLoopGroup object directly
through a helper class which makes it more flexible.
