Helm failure on real cluster

[devdattakulkarni]

When trying with a real cluster we were seeing helm failure where helm was not able to install a chart.

It got fixed after running following command:
kubectl.sh create clusterrolebinding permissive-binding --clusterrole=cluster-admin --user=admin --user=kubelet --group=system:serviceaccounts

We also created a service account for tiller as outlined on [2].

The problem seemed to be that kubeplus pod was not able to reach out to the world. This was fixed by following the suggestion on following link of updating the kube-dns configmap to add 8.8.8.8 and 8.8.4.4 as nameserver.
