Kubernetes-client: Scaling Policies

[Tammo0987]

I wanted to create a new horizontal pod autoscaler with a scaling policy via the api. But am i right there is actually no way to do this. Or is there a workaround?

I think out HorizontalPodAutoscaler is pointing to v2beta1 right now
https://github.com/fabric8io/kubernetes-client/blob/cf186055d12925d5abf78d534db6c0f5618ecec9/kubernetes-model/cmd/generate/generate.go#L38

This feature is supported by v2beta2 apiGroup. We can modify this in model if it's fully backward compatible with v2beta1

Although documentation clearly states this feature is in 1.17, as you can see in the source code, it's not available in the tagged release in GitHub.

1.17 tag:
No Behavior field available:

Nonetheless I'll submit a PR with the update to v2beta2 so that our stays current.
