RDO provides all of the OpenStack services, clients, libs and their
dependencies self-contained in it's repositories.
We have had users that were impacted by sudden updates from EPEL
when it was enabled because EPEL provided a more up-to-date version.
Packages may also be found in both the delorean and delorean-deps
repositories. yum-plugin-priorities will ensure the right package
candidates are chosen for installation.
