The map func is of type DynamicFormControlModelConfigMapFn which passes the model along with an instance of the service. This is done in order to support recursive calling to fromJSON and other methods for cases like ARRAY.

The motivation behind this PR is to truly support custom controls. Currently, you can only extend known types and the extension is limited, you cannot really add new options to the model. This PR allows mapping model config JSON to a new model class with custom options and configurations.

My use case is a draggable form control which can be enabled from the JSON.
