feat(ops/auto-deploy): Support emergency stops via stop file r/3526
Adds a feature to emergency-stop deploys by simply running `touch /var/lib/auto-deploy/stop`. This can be useful in some situations, especially if there is a process that reconciles service state (so that e.g. stopping the unit's timer would be undone).
