> Now we are using App.StackConfigProperty model for storing static info for configs. It's simple approach but in most cases we are transforming App.StackConfigProperty to plain object before usage. This transform operation takes much time. 
> Storing configs as plain objects can reduce config loading time (mostly at installer and add service) up to 3-4 secs for full stack (on default 3-node cluster). Also this changes allow to simplify logic at some places.
