# NOTE(gibi): The service interface cannot be used to simulate a real
# service restart as the manager object will not be recreated after a
# service.stop() and service.start() therefore the manager state will
# survive. For example the resource tracker will not be recreated after
# a stop start. The service.kill() call cannot help as it deletes
# the service from the DB which is unrealistic and causes that some
# operation that refers to the killed host (e.g. evacuate) fails.
# So this helper method tries to simulate a better compute service
# restart by cleaning up some of the internal state of the compute
# manager.
