By using a class with slots instead of standard dict, we can reduce a lot the memory usage to store the record data in the caches and values. Also we can rely on the data in the cache to exist only for real field which can be used to create a fast path in ModelStorage.__getattr__. As now storing data in the cache has no extra cost, we can store data from the transactional cache in the local. This allow also to have a shorter path in ModelStorage.__getattr__. For more memory efficiency, we remove the record from the cache instead of clearing them. It was better to clear a dict but a record is less expensive to re-instantiate than clearing. issue9369 issue9225 review297861002
