TODOs for Cross-Languaged RPC

Java RPC Server

1. Extract Executor implementation

class Executor {
    Executor(std::function<void(std::buffer &encoded_bytes)> func) :on_request_coming_callback_(func) {
    }

    std::function<void(std::buffer &encoded_bytes)> on_request_coming_callback_;
};

2. C++ RPC Server

class RpcServer {
    void CreateService(service_name service) {
 
    }
    
    Executor executor_ = Executor([](std::buffer &encoded_byte) {
         auto rpc_request = codec_.decode();
         str service = rpc_request.service_name();
         str method = rpc_request.method_name();
         tuple args = rpc_request.args();
         Invoke(service, method, args);
    });

    CppCodec codec_;
    map<service_name, service_instance> services_;
};

Since we should write much code for JNI implementation. It's more graceful to use netty for Java if we define the protocol.
