k8s nodes do not have external IP

[stgleb]

Describe the bug Kubernetes nodes created by control do not have EXTERNAL-IP assigned even though underlying infrastracture has.

To Reproduce Steps to reproduce the behavior:

1. Spin up cluster
2. get kubeconfig on your machine
3. kubectl get no -o wide

Actual result

NAME              STATUS   ROLES    AGE   VERSION   INTERNAL-IP    EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION   CONTAINER-RUNTIME
ip-10-2-129-171   Ready    master   12m   v1.13.4   10.2.129.171   <none>        Ubuntu 16.04.5 LTS   4.4.0-1072-aws   docker://17.6.0
ip-10-2-129-25    Ready    <none>   11m   v1.13.4   10.2.129.25    <none>        Ubuntu 16.04.5 LTS   4.4.0-1072-aws   docker://17.6.0

Expected behavior External IPs are assigned likewise in GKE
