k8s conformance tests forcing pod kube-system to exist

This is a pod that is depending on implementation. For openshift, this pod does not exist, so it's causing the validation to fail. I had to manually create a dummy kube-system pod for test to pass.
So this test should be optional, or allow for some specific test depending on the platform. In openshift is not valid to check for pods, but better to check for cluster operators.
