feat(sdk/backend): add data_source parameter to PVC creation

The kpf.kubernetes SDK now supports creating PVC from a data source.
This feature would enable users to create PVCs with pre-populated data,
aligning with Kubernetes capabilities for cloning or restoring PVCs
from existing volumes or snapshots.

This is how it can be done:

```python
pvc = kfp.Kubernetes.CreatePVC(
    pvc_name_suffix="-foo",
    access_modes=["ReadWriteOnce"],
    size="100Gi",
    data_source={"api_group": "snapshot.storage.k8s.io",
        "kind": "VolumeSnapshot",
        "name": "my-snap",
    },
)
```

Hi @leseb. Thanks for your PR.

I'm waiting for a kubeflow 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
