Open Stack

Hi Suro,

Sorry for late. IMHO, even the "magnum service-list" is getting data from
DB, but the DB is actually persisting some data for Kubernetes service, so
my thinking is it possible to change "magnum service-list" to "magnum
k8s-service-list", same for pod and rc.

I know this might bring some trouble for backward compatibility issue, not
sure if it is good to do such modification at this time. Comments?

Thanks
