Deleting a Storage Backend

Do not delete a storage backend when a volume management operation is being performed on it.

Delete the StorageBackendClaim.
```
kubectl delete sbc backend-demo -n huawei-csi
```
After the StorageBackendClaim is deleted, the controller automatically deletes the associated StorageBackendContent.
Check whether StorageBackendContent is deleted.
```
kubectl get sbct
```
If the associated StorageBackendContent is no longer listed, the deletion is successful.

Run the following commands to manually delete the associated ConfigMap and secret:

kubectl delete configmap backend-demo -n huawei-csi
kubectl delete secret backend-demo -n huawei-csi
