Comment 19 for bug 1895822

really not sure about this yet but ...

I started looking for things that are in Ussuri but no Train... I compared that

        * https://opendev.org/openstack/tripleo-heat-templates/commits/branch/stable/ussuri/environments/standalone/standalone-tripleo.yaml
        * https://opendev.org/openstack/tripleo-heat-templates/commits/branch/stable/train/environments/standalone/standalone-tripleo.yaml

in particular this commit seems interesting and missing in train: https://opendev.org/openstack/tripleo-heat-templates/commit/c712355e4bae4ef2fc1b83e5603c0364dbd50a78 * Deprecate Keepalived service https://review.opendev.org/#/c/657067/

I just cherry-picked it to train
https://review.opendev.org/755059 for testing/sanity but as i said... not sure that's it yet.
