Create stable branches on the auto-deploy path
With auto_deploy_on_security enabled, we can't create stable branches on Canonical from an auto-deploy branch that only exists on Security. Instead, we create them on the same remote and then rely on SyncRemotesService, run at the point of publishing, to push the stable branches to the Canonical repositories.
