The stein version of python-oslo.messaging (9.0.0+) has removed
the following config options from the [oslo_messaging_rabbit]
section:
rabbit_host, rabbit_port, rabbit_hosts, rabbit_userid,
rabbit_password, rabbit_virtual_host rabbit_max_retries, and
rabbit_durable_queues.
The above change requires a sync from charm-helpers.
Additionally the transport_url directive has been moved to the
[DEFAULT] section.
These have been deprecated since Ocata, therefore this change
will be provided to pre-Stein templates in order to drop
deprecation warnings.
