Description
StateApps.clone execute two slow deep copies. The first one copy all models. The second one copy app configs, that include all apps and the specific app models.
In my application, with ~250 models, this deepcopy is around 5% of migration time. I was able to cleanup StateApps before copy, to not copy all models and apps every operation again.
