Add Kubernetes types support to 3.x version

[ricardozanini]

What would you like to be added:
After the 3.0.0 release, we had to drop Kubernetes API and types support due to the amount of work required to make it work.

Now that we have the implementation for the DSL 1.0.0, it's time to research and add Kubernetes support.

• Adjust the model to support Kubernetes JSON Raw and Objects type
• Add a simple example of a CRD with the DSL embedded
• Validate the CRD in minikube as part of PR checks

Why is this needed:

Most work around Go developers also relates to Kubernetes, so making the SDK compatible with its types adds value to the community and the CNCF landscape.
