I couldn't set up RabbitMQ for Keystone notifications. Debugging the source code shows that for some reason I get no "rabbit" driver (the one I set as notification_driver in keystone.conf) registered as extension in namespase 'oslo.messaging.notify.drivers' -https://github.com/openstack/oslo.messaging/blob/master/oslo/messaging/notify/notifier.py#L133 I couldn't find any instructions how should oslo.messaging._driver.impl_rabbit be configured in Keystone and suppose that it should be done automatically by Keystone itself Is thery any example of configured Keystone and its notifications consumer?
