Grafana dashboard: Kubernetes Persistent Volumes
Description: Custom enhancement of k8s default dashboard for pvc monitoring.

Just custom enhancement of k8s pvc default dashboard:
* you can specify all pvcs in one namespace and see % of usage
* information about pvcs is shown by repeatable dashboards
