Add labels to setup pod, so the logs can be taken via `kubectl logs -l ...`

It would be nice to be able to have arbitrary command to get logs from setup pod

instead of

```
kubectl get pod
kubectl logs ${POD_NAME_FROM_ABOVE_COMMAND}
```

I would like to use

```
kubectl logs -l ${SETUP_POD_LABEL}
```

I would add the following label:

```
sumologic.com/app: setup
```
