Prevent `graphene_django` from converting Django `choices` to `graphene.Enum` constants: ints like 7 are not converted to "A_7", and so on

def patch_graphene_django_choices_converter():
    """
    Prevent `graphene_django` from converting Django `choices` to `graphene.Enum` constants

    Pros:
    - Ints like 7 are not converted to "A_7"
    - Strings like "Some String" are not converted to "SOME_STRING"
    - Values of any other type are kept as is too
    - No more `AssertionError: Found different types with the same name in the schema: FooType, FooType`
      when you have `choices` field `type` of model `Foo` which autogenerates `FooType` enum,
      conflicting with your own `class FooType(DjangoObjectType)`

    Cons:
    - Client loses ability to get list of possible values from server via GraphQL introspection
    (but still can do this via custom resolver)
