existing object replication are not marked as `PENDING` prior to replication.

you can set the storage class of an object via request metadata field `x-amz-storage-class`. MinIO server then honors the storage class by
saving the object in specific number of data and parity drives.

## Storage usage

The selection of varying data and parity drives has a direct impact on the drive space usage. With storage class, you can optimize for high

- [ ] Provide unit tests (under `<subproject>/src/test`) to verify logic.
- [ ] Update User Guide, DSL Reference, and Javadoc for public-facing changes.
- [ ] Ensure that tests pass sanity check: `./gradlew sanityCheck`.
- [ ] Ensure that tests pass locally: `./gradlew <changed-subproject>:quickTest`.

### Reviewing cheatsheet

    This is used internally by FastAPI to make sure anything you return can be
    encoded as JSON before it is sent to the client.

    You can also use it yourself, for example to convert objects before saving them
    in a database that supports only JSON.

    Read more about it in the
    [FastAPI docs for JSON Compatible Encoder](https://fastapi.tiangolo.com/tutorial/encoder/).
