Add API for easily getting all historical events of certain kind (and/or other type of metadata)

without the need to use underlying ActiveRecord directly

```ruby
event_ar = RailsEventStoreActiveRecord::Event.where(event_type: "MenuUpdated").find_each.select { |mu| mu.data["id"] == 72 }.last
event = RailsEventStoreActiveRecord::EventRepository.new.send(:build_event_entity, event_ar)
Catalog::MenuCatalogHandler.new.(event)
```
