NODE_IP in certain charts is set to the internal ip address

Prior conversation: #399 (comment).

Some charts refer to setting NODE_IP to the following.

export NODE_IP=$(kubectl --namespace default get nodes -o jsonpath="{.items[0].status.addresses[0].address}")

A quick search (https://github.com/kubernetes/charts/search?utf8=%E2%9C%93&q=NODE_IP) reveals that quite a few charts are doing this.

Depending on your network setup, this may be an internal ip address or an external ip address. In my case it's internal.

kubectl --namespace default get nodes -o jsonpath="{.items[0].status.addresses[0]}"

map[address:10.142.0.2 type:InternalIP]%

A better approach might be to inspect the type to see if it's internal or external. If you have two or more external address, just return the first one.
