fix: Changes GetObjectAttributes action xml encoding root element to GetObjectAttributesResponse. Adds input validation for x-amz-object-attributes header. Adds x-amz-delete-marker and x-maz-version-id headers for GetObjectAttributes action. Adds VersionId in HeadObject response, if it's not specified in the request
