Do not force remove containers

Paunch does docker/podman rm -f, when removes containers. It seems it
returns too early, having some leftovers (like docker service
endpoints) behind or pending for it to be removed later, in case of
big fat deamons.

Long story short, don't do rm -f and allow it to do its job gracefully
and without a hurry.
