Please add support for nesting groups in the form-control. 

As written on your page https://docs.telerik.com/kendo-ui/controls/form/groups nesting of groups is not supported.  

As we are developing a highly configurable software we have the need to edit properties of json-objects via UI for the needs of our customers. A schema for validating fields and so on exists, but unfortunately we cannot use "form"-Control because the objects do have nested objects in multiple hierachy levels. 

Therefore nesting of groups would be really great.
