Registry types inconsistency

Encoder generate_latest (for example) accepts registry of CollectorRegistry type but it doesn't accept registry of RestrictedRegistry type so it is not consistent. I guess RestrictedRegistry class should inherit CollectorRegistry class because instance of it can be passed to encoders (maybe not only encoders).

Another option is to inherit RestrictedRegistry class from Collector class because CollectorRegistry is inherited from this class, but then anything that accepts CollectorRegistry type should be changed to accept Collector type.

Commencez par le point d’entrée de l’encodeur generate_latest et comparez sa gestion de CollectorRegistry avec celle de RestrictedRegistry. Déterminez la relation prévue entre les types de registre et vérifiez que la conception choisie rende RestrictedRegistry acceptable partout où un CollectorRegistry est attendu.
