Show class name in scheduler and dataviewer remote

[kangz12345]

Feature you want to implement

The current scheduler does not show the class name.
As we are defining many classes in a single module, it would be convenient to show the class name as well.
Also, it would be helpful to show the class name in the remote dataviewer as well.

How the feature is implemented

Beside the file path column, add class name column in the scheduler.
