There's still the setup-job-network-policy, not sure if you wanted to move that as well?

I left that one on purpose. Because it already sits there near all the rest of the setup job helm temoplates.

EDIT: @Panaetius I will actually clean that up as well. I looked at it earlier but did not notice that it opens the metrics port to postgres for everyone. That is not the end of the world but the metrics port on postgres being open to all pods has nothing to do with the setup jobs. So I will just move this as well.

@aledegano @Panaetius this is ready.
