docker_restart_policy: no causes systemd units to not get created and we use it in CI to disable restarts on services. Introducing oneshot policy to not create systemd unit for oneshot containers (those that are running bootstrap tasks, like db bootstrap and don't need a systemd unit), but still create systemd units for long lived containers but with Restart=No. Change-Id: I9e0d656f19143ec2fcad7d6d345b2c9387551604
