Comment 6 for bug 1650026

I found not all networking commands broken, for example: openstack network set --help, it's ok, but openstack network list --help failed.

Exception will be raised from self.app.client_manager.is_network_endpoint_enabled() method, the method have to get service catalog by a whole authentication, the key point is here[1], auth_type and config["auth"] are mismatch, "username" and other auth info are passed into token_endpoint.Token to initial.
