Use CI built RPMs for CentOS7

There is no official RPM packages for AFS on CentOS7 at this point.
Openstack builds some for us with
I53e8267b2a0fc31589dd3a1f3e3f3a86175a2e15; modify the installation to
point to this repo.

I have tested this locally on a devstack-centos7 node against the
built rpm repo [1].  The puppet run took a long-ish ~5 minutes as it
has to build the kernel modules via dkms.  However, after this, I
could access the afs mount [2].
