unloads Git HTTP traffic from the GitLab Rails app (Unicorn)

 gitlab-workhorse was designed to unload Git HTTP traffic from the GitLab Rails
 app (Unicorn) to a separate daemon. It also serves 'git archive' downloads for
 GitLab. All authentication and authorization logic is still handled by the
 GitLab Rails app.
 .
 Architecture: Git client -> NGINX -> gitlab-workhorse (makes auth request to
 GitLab Rails app) -> git-upload-pack
