Source PR Description (pensando/gpu-operator#1403):

On OpenShift 4.19/4.20 (K8s 1.32/1.33), the resource.k8s.io/v1 API is not available — only v1beta1 or v1beta2. The hardcoded v1 GVK caused DeviceClass creation to silently fail, breaking all DRA tests.

Use the discovery client to probe for the highest available API version (v1 > v1beta2 > v1beta1) before creating the DeviceClass.

Cherrypick triggered by: ACP-Automation

On OpenShift 4.19/4.20 (K8s 1.32/1.33), the resource.k8s.io/v1 API is
not available — only v1beta1 or v1beta2. The hardcoded v1 GVK caused
DeviceClass creation to silently fail, breaking all DRA tests.

Use the discovery client to probe for the highest available API version
(v1 > v1beta2 > v1beta1) before creating the DeviceClass.

Verified on OCP 4.19 (K8s 1.32): operator discovers v1beta1 and creates
the DeviceClass successfully.

(cherry picked from commit 7fae45ad8cb77a4af61f38933a56070685b995f1)
