Cleans up kube-proxy iptables via daemonset (must be manually deleted afterwards), use:

kubectl create -f kube-proxy-cleanup.ds.yaml
# Wait some secs, can peek for exit_status=0 with:
## kubectl logs --namespace=kube-system -l k8s-app=kube-proxy-cleanup
kubectl delete -f kube-proxy-cleanup.ds.yaml
