auto-update: simple rollback
Add support for simple rollbacks during `podman auto-update`. Rollbacks are enabled by default. If a systemd unit cannot be restarted after an update, the previous image will be retagged and the unit will be restarted a second time. Add system tests for rollbacks. Also fix a bug in the restart sequence; we have to use the channel to actually know whether the restart was successful or not. NOTE: To make rollbacks really useful, users must run their containers with `--sdnotify=container` such that the containers send the ready message over the (mounted) socket. This way, restarting the systemd units during auto update will block until the message has been received (or a timeout kicked in). Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
