Add an option to set root password
Currently a default password is set which is not a good practice and requires keeping gitlab private before unleashing it public after changing the password manually.
Can we add a directive for gitlab.rb to set the password as desired. It would be great if this could be changed via a reconfigure but at least an initial set when doing bundle exec rake gitlab:setup RAILS_ENV=production GITLAB_ROOT_PASSWORD=foo would be good enough.
