It's working fine now but by making it more explicit we can make tools
like 'The Silver Searcher' to parse properly the .gitignore file

in order to have it the same way like in omnibus

- Offloads uploading to GitLab Workhorse
- Use /authorize request for fast uploading
- Added backup recipes for artifacts
- Support download acceleration using X-Sendfile

Whenever i'm working on GitLab I have redis running, but redis is
generating a db dump file called dump.rdb, I dont think that should be
checked in, so it should be on the gitignore list

envrc files are created when you use direnv (Its recommended in
combination with spring, see: https://github.com/rails/spring#setup)

Store the secret token in a .gitignored file called ".secret", which is
created by the initializer if it doesn't exist.
