> 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.
