What would you like to be improved?

Currently, the streamServer of netty and grpc server are created in the different places. From my prospective, we could introduce HybridRpcServer to implement ServerInterface for GRPC_NETTY.

In the HybridRpcServer, the grpc and netty should be started.

Interested, but I've encountered a very serious #1472 issue, still working on it. Can you help me fix this issue first? It is a very serious bug. This results in our inability to use it on a large scale in production.
