Make container update override headers persistent
Whatever container update override etag is sent to the object server with a PUT must be used in container updates for subsequent POSTs. Unfortunately the current container update override headers (x-backend-container-update-override-*) are not persisted with the object metadata so are not available when handling a POST. For EC there is an ugly hack in the object server to use the x-object-sysmeta-ec-[etag,size] values when doing a container update for a POST. With crypto, the encryption middleware needs to override the etag (possibly overriding the already overridden EC etag value) with an encrypted etag value. We therefore have a similar problem that this override value is not persisted at the object server. This patch introduces a new namespace for container override headers, x-object-sysmeta-container-update-override-*, which uses object sysmeta so that override values are persisted. This allows a general mechanism in the object server to apply the override values (if any have been set) from object sysmeta when constructing a container update for a PUT or a POST. Middleware should use the x-object-sysmeta-container-update-override-* namespace when setting container update overrides. Middleware should be aware that other middleware may have already set container override headers, in which case consideration should be given to whether any existing value should take precedence. For backwards compatibility the existing x-backend-container-update-override-* style headers are still supported in the object server for EC override values, and the ugly hack for EC etag/size override in POST updates remains in the object server. That allows an older proxy server to be used with an upgraded object server. The proxy server continues to use the x-backend-container-update-override-* style headers for EC values so that an older object server will continue to work with an upgraded proxy server. x-object-sysmeta-container-update-override-* headers take precedence over x-backend-container-update-override-* headers and the use of x-backend-container-update-override-* headers by middleware is deprecated. Existing third party middleware that is using x-backend-container-update-override-* headers should be modified to use x-object-sysmeta-container-update-override-* headers in order to be compatible with other middleware such as encryption and to ensure that container updates during POST requests carry correct values. If targeting multiple versions of Swift object servers it may be necessary to send headers from both namespaces. However, in general it is recommended to upgrade all backend servers, then upgrade proxy servers before finally upgrading third party middleware.
