Implement basic volume backup and restore mechanism This commit implements three new services, specifically: - The `container-volume` service, which applies to a specific volume name and ensures this exists. This is mainly useful as a dependency to other services, as Podman will create named volumes itself if needed. - The `container-volume-backup` service, which creates a `tar.gz` snapshot of the given volume's contents in `/var/lib/backups`. - The `container-volume-restore` service, which populates an empty volume from a pre-existing file in `/var/lib/backups`, presumably created by `container-volume-backup`. These are then be used to automatically create volume snapshots every 12 hours, rolling over every 7 days.

Set generic Podman defaults and per-service log IDs Defaults for Podman that were previous applied as command-line arguments to all `podman run` or `podman create` invocations are now specified in a dedicated configuration file. Services are also better identified against their name rather than the generic `podman` ID derived from the `ExecStart` invocations.
