[New-bugs-announce] [issue17303] Fix test discovery for test_future*

[Zachary Ware]

New submission from Zachary Ware:

Here's the fix for test discovery of test_future* (particularly test_future3).  Without the patch, running 'python -m unittest discover Lib/test/ "test_future*"' results in an error in test_future3.py, due to test_future.py's FutureTest.test_future3 removing test_future3 from sys.modules by way of support.unload.  The patch replaces all instances of support.unload with a support.CleanImport context manager.

The patch also replaces test_main() in all test_future*.py modules, just for good measure.
