Yeah, right now in my testing I'm cheating a bit and running a yum update
before running the undercloud upgrade CLI, because the overcloud prepare
command fail. I'll try to make something cleaner when I've got something
3) Run openstack undercloud upgrade --use-heat, that underneath will: stop

So until now I was trying to avoid this situation and NOT running the
upgrade_tasks, because I think this is not needed in the case of Queens to
Rocky (to a containerized undercloud).
But if we hit more situations similar to this mysql thing, yes indeed we
might need to consider it more seriously.
I really like the idea of just running deploy tasks... as the deployment is
supposed to be idempotent.
Thanks for the feedback so far,
