UPSTREAM: <carry>: PVC DataSource support

[j-griffith]

This pulls in support for specifying object of kind
PersistentVolumeclaim as a DataSource in pvc create manifests,
enabling clone operations for CSI plugins that support it.

This PR does not enable the featuregate but just pulls it in to the vendored k8s base.

Hi @j-griffith. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@j-griffith i think we need an upstream PR to add to the UPSTREAM: <PR#> part of this, then we can review / merge this.. (assuming its landed upstream as is being cherry picked now).
