Add more kubernetes Service tests (#62581)

* Add more kubernetes Service tests

Services can often go wrong, and one of the main motivations for
apply was being able to correctly modify them, so more tests are good

* Remove a port from a service for k8s testing

* Add a Service check mode to k8s tests
