default sync metadata changes on a object version marked `REPLICA` back to source. This requires a setting in the replication configuration called [replica modification sync](https://aws.amazon.com/about-aws/whats-new/2020/12/amazon-s3-replication-adds-support-two-way-replication/).

For active-active replication, automatic failover occurs on `GET/HEAD` operations if object or object version requested qualifies for replication and is missing on one site, but present on the other. This allows...

- The DaemonSet, Deployment, ReplicaSet, and StatefulSet kinds
  are now in the apps/v1beta2 group and version.

- The apps/v1beta2 group version adds a Scale subresource for the StatefulSet
kind.

- All kinds in the apps/v1beta2 group version add a corresponding conditions
  kind.

#### Behavioral Changes

 - For all kinds in the API group version, a spec.selector default value is no longer
