replication can be viewed by doing a GET/HEAD on the object version - it will return a `X-Minio-Replication-DeleteMarker-Status` header and http response code of `405`. In the case of permanent deletes, if the delete replication is pending or failed to propagate to the target cluster, GET/HEAD will return additional `X-Minio-Replication-Delete-Status` header and a http response code of `405`.
