Move pod jobs to parallel execution
Make Podman pod operations that do not involve starting containers (which needs to be done in a specific order) use the same parallel operation code we use to make `podman stop` on large numbers of containers fast. We were previously stopping containers in a pod serially, which could take up to the timeout (default 15 seconds) for each container - stopping 100 containers that do not respond to SIGTERM would take 25 minutes. To do this, refactor the parallel operation code a bit to remove its dependency on libpod (damn circular import restrictions...) and use parallel functions that just re-use the standard container API operations - maximizes code reuse (previously each pod handler had a separate implementation of the container function it performed). This is a bit of a palate cleanser after fighting CI for two days - nice to be able to return to a land of sanity. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
