Subject: image rm: allow for force-remove infra images

Force removal of images will also remove associated containers.
Historically, infra containers have been excluded resulting in
rather annoying errors, for instance, when running `rmi -af`.

Since there is not reasons to exclude infra containers, allow for
removing the entire pod when an infra image is force removed.
