[keycloak-user] Keycloak behind 2 Nginx reverse proxies (HTTPS -> HTTP)

[Stian Thorgersen]

This is not required for reverse proxy and would also prevent the ability
to have multiple endpoints for the same server. If the reverse proxy and
Keycloak is configured correctly it will use the correct URL as seen by the
reverse proxy.
