RPM Support

• a containerized pulp based on pulp-ci-centos image with:

pulpcore-3.13.0 pulp-rpm-3.13.0

I am not sure whether it's a Pulp bug or a CDN data error, but RHEL6 i386 and x86_64 repo syncing repeatedly fails with this error. The repositories are synced with mirror=True and the distribution is set to point to repository (so that the latest repo is always distributed).

Repo: Red Hat Enterprise Linux 6 Server from RHUI (RPMs) (6Server-i386)
