Add some sort of root-checker to gitlab-ctl reconfigure
Summary
I've learned that root is required for gitlab-ctl reconfigure. I'm still able to execute the command as a non-root user, but it will eventually fail at the first thing that my user doesn't have permissions to do.
Proposal
I'd like to see some sort of checking in the reconfigure script that checks to see if it was ran as root, then exits with an error if not.
