ctlptl delete sometimes locks up docker desktop

need to get repro steps on this

One thing I've seen is delete getting into a weird state when I use ctlptl delete -f cluster-with-registry.yml it'll delete the cluster but leave the registry, and then with the registry still in place there ends up being a network collision if you go back and try to ctlptl apply -f cluster-with-registry.yml.

aggressively stopping related containers and using docker container prune followed by docker network prune generally gets me out of that state.
