Make kingress conformance amenable to KinD (#139)

* Make kingress conformance amenable to KinD

Two main changes:
1. Use `imagePullPolicy: IfNotPresent` to support preloading the test images with `ko` + `kind.local`
2. Don't require the service exposed in the kingress status to have type LoadBalancer when we've been handed an `--ingressendpoint`.  This is indicative of local environments like KinD or minikube where the `type: LoadBalancer` service may have been changes to `type: NodePort`.
