Support for specified interface IP addresses

[V3rgilius]

I created a topology using examples/gobgp/gobgp.pb.txt, but I can't ping through from r1 to r2 (I changed the router-id of both nodes). I noticed that there's hardly a way to specify IP address of pods' interfaces. The interface ip can be specified by adding a Kubernetes object to a cluster with meshnet-cni installed, but it cannot be done in a kne deployed cluster by the same method. Is it because the localip and peerip remain empty strings in this code?

	UID: int(ifc.Uid),
	LocalIntf: ifcName,
	PeerIntf: ifc.PeerIntName,
	PeerPod: ifc.PeerName,
	LocalIP: "",
	PeerIP: "",
	})
