Enhance the E2E test to be runnable against remote clusters on e.g. AWS EKS (#1610)

Browse Source 
This contains apparently enough changes to the current E2E test code to make it runnable against remote Kubernetes clusters. I was actually able to make the test passing against my AWS EKS based test clusters with these changes. You still need to trigger it manually from a local checkout of the ARC repo today. But this might be the foundation for automated E2E tests against major cloud providers.
