Add storage.k8s.io/v1 API

v1 API is direct copy of v1beta1 API. This v1 API gets installed and exposed in this PR, I tested that kubectl can create both v1beta1 and v1 StorageClass.

~~Rest of Kubernetes (controllers, examples,. tests, ...) still use v1beta1 API, I will update it when this PR gets merged as these changes would get lost among generated code.~~ Most parts use v1 API now, it would not compile / run tests without it.

**Release note**:
```
Kubernetes API storage.k8s.io for storage objects is now fully supported and is available as storage.k8s.io/v1. Beta version of the API storage.k8s.io/v1beta1 is still available in this release, however it will be removed in a future Kubernetes release.

Together with the API endpoint, StorageClass annotation "storageclass.beta.kubernetes.io/is-default-class" is deprecated and  "storageclass.kubernetes.io/is-default-class" should be used instead to mark a default storage class. The beta annotation is still working in this release, however it won't be supported in the next one.
