_This collector does not yet have any useful queries added, we would appreciate your help adding them!_
Attach labels namespace/pod/container fow windows container metrics.
```
# kube_pod_container_info(a metric of kube-state-metrics) has labels namespace/pod/container/container_id for a container, while windows container metrics only have container_id.
# Attaching labels namespace/pod/container for windows container metrics, is useful to query for windows pods.
