Public bug reported:

The current implementation always tries to get a transport from
oslo.messaging assuming the transport_url option has been set. This is
done to keep backwards compatibility. However, since the default
`rpc_backend` is rabbit, it'll always try to load such driver. The
problem raises when `kombu` is not installed and the `notifier_strategy`
is set to qpid. This will make glance-api fail because it'll try to load
the rabbit driver *before* loading the qpid one.
