Add some clarification for some files under config/*

Add some clarification for some files under config/*

I didn't add a lot of them because I am not very familiar about how they
work and I am not sure if we really need to explain files like
config/database.yml because if you know Rails you must know how
that works.

At any rate, I think this is a beginning and we could keep documenting
more files in the future.

Update github.md

Hi, I ran into a few pitfalls while I enabled OmniAuth to be able to migrate repos from github to my omnibus-gitlab instance today, so here are my findings:

These docs state thate the default authorization callback URL is `'${YOUR_DOMAIN}/import/github/callback'`, but the screenshot only shows `'${YOUR_DOMAIN}'`, which works, so I removed the ambiguity.

When editing `gitlab_rails['omniauth_providers']` for github.com, you have to omit the `"url" => "https://github.com/",` part, otherwise it won't work (OmniAuth will stay deactivated). This is backed by the configuration details of the "from-source-installation" which also omits the url in the `yml` file.

After changing the `gitlab.rb` file, `sudo gitlab-ctl reconfigure` needs to be run, which is missing in the docs.

Following the updated version of this documentation I was able to enable OmniAuth.

If anything I edited is wrong, please correct me, as I don't know how the "from-source-installations" would react to my changes.

Best regards,
Florian
