Backport gitlab.yml.example from EE

To make this happen, we need to conditionally add the group_saml
strategy when running tests, but only on EE. This requires some changes
to Gitlab.ee? so that it can be used before/without loading the Rails
environment. We also have to change how we require a few files, so this
can run outside of Rails.
