Automatic merge from submit-queue

Use preferred group version when discovery fails due to 403

```
kubectl get pods --as bob
```
Returns:
```
error: failed to negotiate an api version; server supports: map[], client supports: map[autoscaling/v1:{} rbac.authorization.k8s.io/v1alpha1:{} federation/v1alpha1:{} batch/v1:{} v1:{} authentication.k8s.io/v1beta1:{} apps/v1alpha1:{} componentconfig/v1alpha1:{} authorization.k8s.io/v1beta1:{} batch/v2alpha1:{} extensions/v1beta1:{} policy/v1alpha1:{}]
```
It should return:
```
User "deads" cannot "impersonate" "users" with name "bob" in project ""
```

`serverVersions` is empty when discovery fails, thus we fallback to the `preferredGV`.
