This adds support for Services that don't have selectors.

  • respect labels/annotations
  • add unit test for managed EndpointSlice

Checklist prior to review

  • Link to relevant issue as well as docs and UI issues --
  • This will not break child repos: it doesn't hardcode values (.e.g "kumahq" as a image registry) and it will work on Windows, system specific functions like syscall.Mkfifo have equivalent implementation on the other OS --
  • Tests (Unit test, E2E tests, manual test on universal and k8s) --
    • Don't forget ci/ labels to run additional/fewer tests
  • Do you need to update UPGRADE.md? --
  • Does it need to be backported according to the backporting policy? (this GH action will add "backport" label based on these file globs, if you want to prevent it from adding the "backport" label use no-backport-autolabel label) --

@lahabana it's a missing feature. The impetus was that there are new Gateway API tests that test forwarding to Services with manually managed EndpointSlices. Which will prevent us from moving to v1.1
