This leverages conmon's ability to proxy the SD-NOTIFY socket. This prevents locking caused by OCI runtime blocking, waiting for SD-NOTIFY messages, and instead passes the messages directly up to the host. NOTE: Also re-enable the auto-update tests which has been disabled due to flakiness. With this change, Podman properly integrates into systemd.
