cephadm: Introduce unit.stop

Reason is we now have to stop two containers named differently. This is possible
with `bash -c ... echo %i | tr . -`. But we're not gainig anything readability
compared to putting it into a unit.stop script.

As not all daemons have this stop script, we still have to call podman for old daemons.
