This backport changes made by EE to the files in the scripts/ directory.
This comes with a few changes to some scripts to make them work in the
single codebase setup.
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.
To be used as a feature flag for GitLab.com-only features, such as
welcome emails.
We will be careful to only use this to disable features or functionality
that do not make sense for any installations that aren't GitLab.com. We
will not use this to restrict features from other installations or keep
them "exclusive" to GitLab.com.
