The configuration options registered by oslo.messaging should not be
directly relied upon by users of the library, since those config option
names could change in future.
Add an API which allows API users to override specific configuration
options e.g.
self.messaging_conf = self.useFixture(messaging.ConfFixture(cfg.CONF))
self.messaging_conf.transport_driver = 'fake'
