Improved out of the box `SecondaryToPrimary` mapping for `KubernetesDependentResource`.

It basically won't work with default mapper.

Throw event an exception?

Discussed this on weekly, we could also approach this problem in a different way. That Kubernetes dependent resource might support in addition to owner reference handling also adding labels if the owner reference cannot be added (resources are in different namespace).

Basically with these two different approaches we cover every case. So should be supported out of the box. But also there should be a possibility for a custom approach.
