                                         If a domain(-name) is set, it will automatically filter out all messages from other domains.
                                         If no domain(-name) is set, messages from all domains will be received.
            sub_topic_domains (Dict[str, str]): change subscribed to topics to listen to a specific domain 
                                                (e.g. 'erase'/append a domain for a specific topic)

            ds_host_addr (str): IP-address of the parent `DialogSystem` (default: localhost)
            sub_port (int): subscriber port following zmq's XSUB/XPUB pattern
            pub_port (int): publisher port following zmq's XSUB/XPUB pattern
            protocol (string): communication protocol with `DialogSystem` - has to match!
                               Possible options: `tcp`, `inproc`, `ipc`
            debug_logger (DiasysLogger): If not `None`, all messags are printed to the logger, including send/receive events.
                                         Can be useful for debugging because you can still see messages received by the `DialogSystem`
                                         even if they are never forwarded (as expected) to your `Service`.
            identifier (str): Set this to a *UNIQUE* identifier per service to be run remotely.
                              See `RemoteService` for more details.
