Remove heapster manifests from addons

Browse Source 
* Heapster addon powers `kubectl top`
* In early Kubernetes, people legitimately used and expected
`kubectl top` to work, so the optional addon was provided
* Today the standards are different. Many better monitoring
tools exist, that are also less coupled to Kubernetes "kubectl
top" reliance on a non-core extensions means its not in-scope
for minimal Kubernetes clusters. No more exceptionalism
* Finally, Heapster isn't that useful anymore. Its manifests
have no need for Typhoon-specific modification
* Look to prior releases if you still wish to apply heapster

# Heapster
[Heapster](https://kubernetes.io/docs/user-guide/monitoring/) collects data from apiservers and kubelets and exposes it through a REST API. This API powers the `kubectl top` command.
## Create
```sh
kubectl apply -f addons/heapster -R
```
## Usage
Allow heapster to run for a few minutes, then check CPU and memory usage.
```sh
kubectl top node
kubectl top pod
```
