This patch moved the remaining RPC calls away from the MDNS service to the Worker and re-worked them to better match the patterns used in the Worker. This means that the MDNS service now only handles incoming DNS queries. In addition the metrics backend has been removed as it was only used by the MDNS RPC implementation and the monascastatsd implementation no longer serves a purpose.
