Support DictField with child

[zach-waggoner]

There doesn't seem to be any way to represent dictionaries with a known value type. For example, this:

class ExampleSerializer(serializers.Serializer):
    dictionary = serializers.DictField(child=serializers.IntegerField())

produces this:

Example:
  type: object
  properties:
    dictionary:
      type: object
      additionalProperties: {}

It would be nice if it would instead produce this:

Example:
  type: object
  properties:
    dictionary:
      type: object
      additionalProperties:
        type: integer

good catch! i think this should be an easy addition for the basic cases
