    Refactored service layer

    Service layer has been simplified by removing abstraction
    and making the implementation more in line with other
    OpenStack projects.

    Moved Heartbeat code out of Service class and
    into the console scripts. We only need one instance
    of the Heartbeat Emitter.

    Cleaned up the WSGI code by making use of the
    reusable oslo_service.wsgi code.

    * Added Heartbeat to designate-sink.
    * Cleaned up and refactored Service layers.
    * Fixed various bugs e.g. errors on shutdown.
    * Removed deprecated options host, port etc.
    * Simplified Heartbeat implementation.

    Closes-Bug: #1442141
