Stan Lagun 05edab3661 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.
