this is similar to handler.register_service but for client-server style applications. register_service is not appropriate for such applications becuase normally the client does not consume (in the sense of set_ev_cls) asynchronous events from the server.
note: this automatically load the server only if "api" module is directly loaded from the module defining the client application.
