workqueue. In case of parallelism > 1, if there are multiple new failures in a reconciliation cycle, all the failures are taken into account to compute the back-off. Previously, the back-off kicked in for all types of failures; with this change, only pod failures are taken into account. If the back-off limits exceeds, the job is marked as failed immediately; before this change, the job is marked as failed in the next back-off.

 - The metric `storage_operation_errors_total` is not removed, but is marked deprecated, and the metric `storage_operation_status_count` is marked deprecated. In both cases the `storage_operation_duration_seconds` metric can be used to recover equivalent counts (using `status=fail-unknown` in the case of `storage_operations_errors_total`).
