Feature Description

• One-line feature description (can be used as a release note): CSI volumes can only be referenced via PV/PVC today. This works well for remote persistent volumes. However, we would like CSI to be used to create local ephemeral volumes (e.g. volumes to inject identity information in to a pod), and these types of volumes should be able to be referred to directly in pod spec (without PV/PVC).
