rgw_sal_motr : [CORTX-34168] Modified response fields of DeleteObjects API (#426)

Problem: DELETE Objects API should return Deleted key, DeleteMarker and DeleteMarkerVersionId in response when a delete marker is created for an object in a versioned bucket

Solution: Set the delete_marker variable to true to get "Deleted key, DeleteMarker and DeleteMarkerVersionId" in the response.
