That diff is not intended to be landed as is but is rather a proof of concept regarding
the integration of Keycloak in swh-web.
Keycloak is an opensource solution for adding authentication to applications and securing
services with minimum fuss.
Instead of using the Django authentication system, every operations related to users
management are delegated to Keycloak.
That diff is an experiment of using it to authenticate users who make requests to the
swh web api and lift the rate limiting if they have the proper permission.
To test that new feature, you can use the docker-compose environment by following the
instructions located in diff D2131.
