Workaround repopriority of yum local repo.
Workaround repopriority of yum local repo.

Because of issues with package name differences vps are
setup to use repopriority and our local repo (which has
some ceph/librados stuff in it) gets high priority so
the ceph.repo that is created on the machine from
ceph-release basically gets ignored. This change makes
it so ceph.repo is the same priority level as our local
repo.
