Add key serializer's config snapshot to KeyedBackendSerializationProxy

    Details

      Description

      Currently, only the key serializer is included in what's written for a keyed state backend in checkpoints. The namespace and state serializer already have their config snapshots included in the individual registered state's metainfo.

      We should also include the configuration snapshot of the key serializer in KeyedBackendSerializationProxy so that we can also be flexible in allowing migration / transformation of the key in the future.
