      - Disables maintenance mode for an app
      - Specify the one-off workload through `one_off_workload` in the `.controlplane/controlplane.yml` file
      - Optionally specify the maintenance workload through `maintenance_workload` in the `.controlplane/controlplane.yml` file (defaults to 'maintenance')
      - Maintenance mode is only supported for domains that use path based routing mode and have a route configured for the prefix '/' on either port 80 or 443
