Extension models should have buildable references to core kubernetes-model types.

[iocanel]

Methods like:

• withNewMetadata
• withNewContainer
• addNewContainer

and so on are no longer generated, due to the absence of BuildableReference to types like:

• ObjectMeta
• Container
• etc

While this is relatively easy to work around, having those method is one of the little things that add to the overall experience.

The root cause of this issue seems to be the removal of the specific annotators.

Probably merging the ModelAnnotator with the others (or making it extend form KubernetesCoreTypeAnnotator), or at least move it to the same package would make sense too.
