When given the "run" argument, in addition to launching `podman system service` in the background, also start a small periodic maintenance script. It's only job is to clean up stale images, containers, and volumes from old jobs. Currently hard-coded to trigger every 2 days, this could be tweaked via build-args or env. var.
