Rather than tieing this to the migration, just do them.
The afs package build script changed slightly - it now publishes to
tarballs.openstack.org/project-config/package-afs-centos7 instead of
tarballs.openstack.org/package-afs-centos7 so that the normal artifact
publication base job can be used.
The existing package-afs-centos7 has been copied on tarballs.openstack.org to
project-config/package-afs-centos7 so that this will not cause a rebuild.
