Authentication-validator library

This is a spring service which validates jwt access tokens issued by keycloak.
When it encounters an invalid token, it throws a ResponseStatusException with the corresponding HTTP status.
This service is used by all Gamify-IT backends to validate the users and to require authentication for specific routes.
