podman system prune would leave pods be, and not prune them if they were stopped. Fix this by adding a `podman pod prune` command that prunes stopped pods similarly to containers. Signed-off-by: Peter Hunt <pehunt@redhat.com>

NAME
podman-system-prune - Remove all unused container, image and volume data
SYNOPSIS
podman system prune [-all|--a] [-force|--f] [-help|--h] [-volumes|--v]
DESCRIPTION
podman system prune removes all unused containers (both dangling and unreferenced), pods and optionally, volumes from local storage.
With the all
option, you can delete all unused images. Unused images are dangling images as well as any image that does not have any containers based on it.
By default, volumes are not removed to prevent important data from being deleted if there is currently no container using the volume. Use the --volumes flag when running the command to prune volumes as well.
OPTIONS
--all, -a
Remove all unused images not just dangling ones.
--force, -f
Do not prompt for confirmation
--volumes
Prune volumes not used by at least one container
