making the helloworld service ready for autoscaling.

Enable autoscaling on both versions of the service:

```bash
kubectl autoscale deployment helloworld-v1 --cpu-percent=50 --min=1 --max=10
kubectl autoscale deployment helloworld-v2 --cpu-percent=50 --min=1 --max=10
kubectl get hpa
```

## Generate load

```bash
./loadgen.sh &
./loadgen.sh & # run it twice to generate lots of load
```
