Include original error in the error message
**What this PR does / why we need it**:
This PR improves error message by including an initial error into it.
Before this change `hack/test-update-storage-objects.sh` was failing with the following error:
>E0326 19:32:28.511136 31378 server.go:456] Failed to create clientset with KUBE_API_VERSIONS="v1,networking.k8s.io/v1,storage.k8s.io/v1beta1,extensions/v1beta1,networking.k8s.io/v1,storage.k8s.io/v1,extensions/v1beta1". KUBE_API_VERSIONS is only for testing. Things will break.
Now it shows also error cause:

KUBE_API_VERSIONS is only for testing. Things will break.
