We want to extend FormSectionProps in this way

export interface FormSectionProps {
  ...
  values?: any;
  onChange(values: any): void;
  onReset(): void;
}

where values are the values of its children and onChange/onReset methods to change children values in bulk.

This is useful inside custom field renderers. It is similar to what it is already possible with ArrayFieldProps.

Ideally, we would like to use some method of redux-form, if possible.
