CE backport for changes in EE MR 14017

See merge request gitlab-org/gitlab-ce!29328

This backports to CE changes to allow the EE model
DesignManagement::Repository to override the #attributes_at method to
provide its own git attributes.

The #attributes_at method was freely available, as it's never called by
anything in the app. It looks like the code that called it got
refactored out of existence in ca66a04f. It was still being called in a
spec
https://gitlab.com/gitlab-org/gitlab-ce/blob/85b29c1c2fa3b94d7371cf454c485457a0756cb1/spec/services/files/create_service_spec.rb#L40
which I've left because with the change in Lfs::FileTransformer in fact
is now again the perfect test!
