Consider hiding imported classes and functions in outline view

[youralmight]

Today, vscode python displays both imported and here-defined methods and classes in the outline view of an opened python file, which results in long and unintelligible outline content like that in this picture.

In fact, there are only 6 functions defined in the given example and all others are imported. If the imported classes and functions can be hidden, the outline view can be much more clearer and it will help a lot in source code reading.
