Array of handlers that rcs uses to manage object versioning.
The RCS service gives a write only interface to different services wanting to save changes to objects.
The RCS service will try to initialize the backend based on GNU RCS, but, if that fails, fall back to the nullrcs handler. The nullrcs handler does not save anything at all.
Configuration parameters that are in use by this service:
$config : \midcom_services_rcs_config
The configuration object for the rcs service.
load_handler( $object) : \midcom_services_rcs_backend
Loads the handler
