Adding support for engine Prepare mode - value is PrepareMode. Adding support for engine Maintenance mode - value is MaintenanceMode. The default value of those configuration keys is Regular, however, this value can be set to PrepareMode/MaintenanceMode in order to prevent new commands from being processed by the backend class.
