Support for v1alpha1 for custom resources definitions

Hi,

I'm trying to use `kubernetes-client` for creating certificates which are of type `Certificate` and kind `certmanager.k8s.io/v1alpha1`

It seems that the custom resources definitions only exposes `v1beta1`, and therefore I'm stuck (or maybe I did not look at the right place).

Is that supported ?

Thanks

The issue names no file, test, or entry point. Start by locating how this JavaScript client exposes Kubernetes custom resource definitions, then trace the version mapping for v1beta1; done means v1alpha1 is exposed and Certificate resources can be created through the client.
