e2e: request to change current approach to get logs

e2e tests use this approach to get pod logs:
```
		ginkgo.By("waiting for the IAA demo to succeed")
		f.PodClient().WaitForSuccess(podName, 300*time.Second)

		ginkgo.By("getting workload log")
```

Which is almost useless as nobody is interested in getting logs of succeeded workloads.
We should change this in a way that even if workload fails we can see the logs.
