gobgp client in kube-router docker image does not show peer information

[murali-reddy]

@thoro reported this issue. I tested it out and could reproduce it.

~ # gobgp neighbor
Peer    AS  Up/Down State       |#Received  Accepted
 64512 00:30:53 Establ      |        1         1
 64512 00:31:05 Establ      |        1         1

Problem seems to be with neighbor command only. Global rib shows up fine.

~ # gobgp global rib

From local gobgp client i am able too see the information fine.
