Description
When service to service test is running, istio-ingressgateway on Kind returns 502 with no such host error.
We added retry checker by https://github.com/knative/pkg/pull/2351 but prober should ensure that DNS works as expected.

Contributor guide
Research direction
Start by locating the prober used by the service-to-service test and reproduce the Kind failure involving istio-ingressgateway returning a 502 and "no such host." Compare its behavior with the retry checker from knative/pkg pull request 2351; done means the prober verifies DNS works as expected and the reported failure is prevented or detected clearly.
