> I propose to add a custom Map<String,String> annotation field to
> objects/buckets and keys in Ozone Manager.
> It would enable to build any extended functionality on top of the OM's
> generic interface. For example:
> * Support tags in Ozone S3 gateway
> (https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectGETtagging.html)
> * Support md5 based ETags in s3g
> * Store s3 related authorization data (ACLs, policies) together with the
> parent objects
> As an optional feature (could be implemented later) the client can defined
> the exposed annotations. For example s3g can defined which annotations should
> be read from rocksdb on OM side and sent the the client (s3g)
