[stable/heapster] Match the label in deployment yaml

[caulagi]

The instructions provided by NOTES.txt doesn't work because the label on the deployment doesn't match the label used in NOTES.txt.

$ helm status eyewitness-lamb
LAST DEPLOYED: Thu Feb 22 15:23:44 2018
NAMESPACE: default
STATUS: DEPLOYED

RESOURCES:
==> v1/Service
NAME      TYPE       CLUSTER-IP     EXTERNAL-IP  PORT(S)   AGE
heapster  ClusterIP  100.64.31.201  <none>       8082/TCP  1h

==> v1beta1/Deployment
NAME                      DESIRED  CURRENT  UP-TO-DATE  AVAILABLE  AGE

==> v1/Pod(related)
NAME                                       READY  STATUS   RESTARTS  AGE
eyewitness-lamb-heapster-66f796c55b-q86kh  2/2    Running  0         1h


NOTES:
1. Get the application URL by running these commands:
  export POD_NAME=$(kubectl get pods --namespace default -l "app=heapster" -o jsonpath="{.items[0].metadata.name}")
  kubectl --namespace default port-forward $POD_NAME 8082

And the output of the pod itself from kubectl -

$ kubectl describe pod eyewitness-lamb-heapster-66f796c55b-q86kh

So NOTES.txt looks for the label app=heapster but the pod has the label app=eyewitness-lamb-heapster. This was changed in #2144.

I matched the NOTES.txt to match the label in deployment.yaml (though we could do it the other way round also).
