Add in branch case for puppet-ceph stable/jewel

Since puppet-ceph does not follow the openstack naming conventions, we
need to add a special case so we get the right version of
puppet-openstack-integration checked out. Until we can switch over to
the zuul v3 layout that has this in it as well, we need to update the
legacy job to handle a stable/jewel to stable/pike change
