Kubernetes Custom Upstream DNS

Customize upstream DNS resolution.

Customize the Upstream Nameservers used by kube-dns by Pods when looking up external hostnames from within a Kubernetes cluster. I found that adding custom Upstream Nameservers to my kube-dns solved many issues encountered in in the past with external hostname resolution on individual Pods.
