OSTree Support

I have am syncing 'Red Hat Enterprise Linux Atomic Host Trees' from 'https://cdn.redhat.com/content/dist/rhel/atomic/7/7Server/x86_64/ostree/repo' and it is raising an error:

This appears like a duplicate of https://pulp.plan.io/issues/2552 at first, but it looks like that has already been resolved and should be fixed with the versions used here.
