gitlab: sync gitlab-ce & gitlab-shell settings from omnibus-gitlab

Like 6fd7b987 - pristine copy from omnibus 8.4.4+ce.0-0-g1680742.

The only change is in

    gitlab.yml

The following files stay the same:

    database.yml.erb
    gitlab-rails-config.ru.erb
    gitlab-shell-config.yml.erb
    rack_attack.rb.erb
    resque.yml.erb
    smtp_settings.rb.erb
    unicorn.rb.erb
