Lazily import `traceback` in `logging`

[ByteFlowing1337]

Feature or enhancement

Proposal:

Currently, Lib/logging/__init__.py and Lib/logging/config.py eagerly import traceback, despite it only being used during exception handling. Making this import lazy avoids unnecessary startup overhead and improves initial loading time.

Has this already been discussed elsewhere?

I am not sure it would actually work at finalization time. What if the module gets reified at that time?
