test(e2e) verify clusters without LB providers

Add a test that uses a cluster without a load balancer.

Add support for overriding the KIC image in E2E tests. Loads an
arbitrary image into the E2E test cluster and uses kustomize to replace
that image in test manifests.

Add support for NodePorts and no-IP LoadBalancers (via their NodePort)
when attempting to verify an Ingress.
