Update README.md (#72)

+## Access Kubernetes Dashboard
+As of release 1.7 Dashboard no longer has full admin privileges granted by default, so you need to create a token to access the resources:
+```sh
+$ kubectl -n kube-system create sa dashboard
+$ kubectl create clusterrolebinding dashboard --clusterrole cluster-admin --serviceaccount=kube-system:dashboard
+$ kubectl -n kube-system get sa dashboard -o yaml
