code here moved to KubernetesApiSpec because it's only testing KubernetesApi.
AppVersionRevisionSpec is not testing the failure case inside AppVersionRevision.start

If podname is not set, there is nothing else we can do, but if we try to later use getRevision we get a Future that never completes.

Hmm, maybe we should not return an IllegalStateException, because it's not illegal. It's just missing info causing a degraded state.

yep, that's wrong. Copy-n-pasta wrong.

Fixed.
It turns out that tests were passing even without using the right config. Which makes sense because podname defaults to empty in the reference.conf.
Anyway, I keep the new config just to make it very explicit, but did some clean-up as well.

Noticed today with @franciscolopezsancho, that the versionPromise may never complete forcing users to do some weird future gymnastics to work it around.
