Implement base interface for most Kubernetes objects

[dlaidlaw]

Most of the Kubernetes objects have a set of fields in common:

• kind
• apiVersion
• metadata
• spec

The objects that support this really need to reflect that by implementing an interface and possibly extending a base class.

Looks like OpenAPI supports this but is flagged as experimental. @mbohlool knows much more about the spec & how it's generated for k8s - is this on your radar?

This has to happen via Swagger, I added this:

kubernetes/apiserver#23

To track.

Was any work done on this. This will be very useful
