Add config.included_models

[ramaboo]

We run a large app where 90% of our app is not using Apartment. We really only use it for two tables. This makes config.excluded_models not work so well for us as ever new model we add we have to go and manually exclude it. It would be much simpler if we could do config.included_models instead. Right now we run code like this:

      included_models = %w[Widget Classification]
      manual_exclude = %w[UserRole]
      active_storage = %w[ActiveStorage::Attachment ActiveStorage::Blob ActiveStorage::VariantRecord]
      all_models = ApplicationRecord.connection.tables.map do
        model_name = _1.capitalize.singularize.camelize

        Module.const_defined?(model_name) ? model_name : nil
      end.compact.sort

      config.excluded_models = all_models - included_models + manual_exclude + active_storage
      

But it's not ideal and error prone. I was wondering if there are any plans to support config.included_models or if someone familiar with the code base could point me in a direction for starting that work?

We use this popular gem Rolify (https://github.com/RolifyCommunity/rolify) - which uses an internal table (for some internal join queries), that is not manifested as an ActiveRecord model, and thus there's no way to manifest it as an excluded_models.

An included_models option will make this gem more compatible with other gems.
