offline CRD rendering

[janwillies]

Feature Description

Problem Statement:
I have written a couple ResourceGroups and want to publish the APIs (spec.schema) for documentation purposes. Currently I have to apply the ResourceGroups to kube-apiserver and fetch the generated CRDs.

Proposed Solution:
I would like to render the CRDs offline so that I can include them in my release process

Alternatives Considered:
Applying the ResourceGroups to kube-apiserver and fetching the generated CRDs.
