Implement `__eq__` for CreateFolderParent class

Is your feature request related to a problem? Please describe.

I'm trying to use unittest to check call args:

def test_create_folder_exists(box: BoxClient):
    with patch.object(box.folders, 'create_folder') as mock_create:
        mock_create.side_effect = [
            BoxAPIError(RequestInfo('POST', 'url', {}, {}), ResponseInfo(409, {}), '409'),
            'FolderFull',
        ]
        new_box.create_folder(
            box,
            PARENT_FOLDER_ID,
            'test_folder_829',
            increment=True,
        )
        assert mock_create.call_count == 2
        mock_create.assert_any_call(
                'test_folder_829 (1)',
                CreateFolderParent(PARENT_FOLDER_ID),  # THIS PART IS FAILING
        )

(I'm trying to check that my code increments folder names on collisions, like name (1), name (2), etc.)

Unfortunately, the assertion does NOT pass, because CreateFolderParent doesn't implement __eq__:

In [9]: from box_sdk_gen import CreateFolderParent
In [10]: a = CreateFolderParent('12')
In [11]: b = CreateFolderParent('12')
In [12]: a == b
Out[12]: False

Describe the solution you'd like

Adding basic equality check makes my tests pass:

    def __eq__(self, other):
        if isinstance(other, CreateFolderParent):
            return self.id == other.id
        return False

I guess it would be nice to implement this for all these "arg" classes in the library, as there are lots of them.

Describe alternatives you've considered

I can fix my current issues with deep assert equal of the create_folder_parent.id values.
