refactor login as to be impersonation with better login/logout

Modifies the existing "login as" feature to be called impersonation.

This also adds:

* Application keep track of who is impersonating the user so they can revert back to the original user without having to log out.
* Stores the user profile via `HTTP_REFERER` so you get redirected back to the person you have impersonated once you stop.

Expose builds feature

Expose builds feature in project settings (as feature).

Enable it by default for a new projects.

I deliberately named it builds instead of CI, because we actualy allow to run tests using infrastructure built-in GitLab. I'm free to change it.

If we are ok, I'll add feature tests for it.
