Github integration

As reported by @markus.blatt authentication via github does not work anymore. Should be possible to fix it following https://docs.gitlab.com/ee/integration/github.html.

@markus.blatt Can you check if it is working now?

Nope. After logging into github.com the redirect to https://github.com/login/oauth/authorize?client_id=YOUR+APP+ID&redirect_uri=https%3A%2F%2Fgitlab.dune-project.org%2Fusers%2Fauth%2Fgithub%2Fcallback&response_type=code&scope=user%3Aemail&state=....` raises a 404 error. Maybe the correct client_id is needed?

We should be getting closer. I forgot another option. What happens now? If I try to loign via github a new user with my github name is created and is blocked. What happens in your case?

Works like a charm, now. Thanks.
