e2e: use apiserver view of pods on node instead of kubelet

Conformance tests must not rely on the kubelet API in order to
pass. SchedulerPredicates tests attempt to use the kubelet API
in their BeforeEach, some of which are tagged as Conformance.

Is there a compelling reason to use the kubelet's view of pods
for a given node instead of the apiserver's view of the pods?
