Currently, kube-router just lists all IPVS services on the host and then adds the load balancing service IPs to kube-router-svip blindly. However, this assumes that the only IPVS entries are entries that kube-router has originated and that the user isn't using IPVS.
We want to make sure that we are only creating rules for services that we are authoritative for. So to this end, we now double-check that this is one of our services before adding rules that may effect it.
