Summary

It appears as if `kube_persistentvolume_info` now has a field `ebs_volume_id` that has the underlying `vol-` resource id for the AWS EBS volume behind a volume. If we can collect this we could enhance our OCP on AWS story by directly matching storage costs to the cluster.

UPDATE:

https://docs.openshift.com/container-platform/4.15/storage/persistent_storage/persistent-storage-aws.html

The plug in that is providing unique identifier for the volume is being deprecated in favor of moving to the equivalent Container Storage Interface (CSI) driver. We added a volume using the new CSI driver in our demo account, and discovered that for AWS the csi_volume_handle metric was equivalent to the ebs_volume_id.
