Comment 0 for bug 1838696

"rabbit_use_ssl" is needed instead of "ssl" for the [oslo_messaging_rabbit] config section for versions of python-oslo.messaging used in icehouse->ocata.

This was regressed when fixing https://bugs.launchpad.net/charm-neutron-api/+bug/1817672 which introduced use of section-oslo-messaging-rabbit by ocata templates.

Bug 1817672 was fixed for ocata+ so we should only need to re-introduce "rabbit_use_ssl" for ocata templates.
