Simplification of AUTH_INSTANCE
There were 3 phases: configuration parsing, service definition and service registration. The last two can be merged, since there is no direct external reference to the service of a specific auth system. As a consequence, there is no need for a Register sub-fonctor in AUTH_INSTANCE: service definition and registration occur directly in the Make function, called by instantiate.
