Summary: Trying to add custom `fsType`s, new metadata fields need to be stored. We need a mechanism to migrate existing volume metadata.
Test Plan:
- Install the chart using an older image tag like `36fc480`
- Create and use a pvc
- Verify that the volume's metadata file, located at `/var/csi/rawfile/pvc-.../disk.meta` does not contain the `schema_version` field
- Upgrade the chart to use the image tag `feature-schema-migration`
- Wait until all node pods are upgraded
- Verify that the volume's metadata file contains the new `schema_version` field
