What this PR does / why we need it:

This adds a simple test that creates a pod and a service. It then directs that pod to make a request to itself, but mapped through the service.

This is an oft-missed case when modifying network components. It can indicate bugs in kubelet, kube-proxy, kubenet, and CNI plugins, to name a few.

Release note:

NONE
