    Do not wait for MessageHandlingServer

    Previously oslo.messaging's MessageHandlingServer
    was used as as a murano-engine service in service launcher.
    As a result it's wait() method was called. But after recent
    changes it's wait method is supposed to be call only
    after stop() to wait for graceful message processing to end.
    As a result a warning was printed that stop() didn't finish
    after 30 sec from wait() invocation (because it was never called).

    This commit adds EngineService service implementation
    that has its own wait() and encapsulates MessageHandlingServer
    instance.
