As discussed, adding this issue as a tracker.

I'll go ahead and remove test triggers on k8s prow for this repo.

@Bobgy Thanks for bringing this up, after removing it from k8s prow, I'll make sure to add it into optional-test-infra.

Note, it's already removed from k8s prow

Thanks @Bobgy I'll be working on migrating to optional-test-infra a bit later, kind of busy at this moment
