Support for VolumeSource images in future

[danielloader]

Thought I'd ask early and see, it might even work already!

KEP 4639 recently got pushed into alpha with a working implementation in 1.31 (behind the alpha feature gate).

Just wondering if the existing logic for matching images and tags would work with the object schema found in the docs?

apiVersion: v1
kind: Pod
metadata:
  name: image-volume
spec:
  containers:
  - name: shell
    command: ["sleep", "infinity"]
    image: debian
    volumeMounts:
    - name: volume
      mountPath: /volume
  volumes:
  - name: volume
    image:
      reference: quay.io/crio/artifact:v1
      pullPolicy: IfNotPresent

To summarise, I'd love to be able to patch the .spec.volumes[0].image.reference field with the existing image functionality in kustomize.
