request: create traceback logging rules

[lainisourgod]

Hi!

I'm relying heavily on rich traceback logging in my daily debugging and I usually set show_locals to True to see what happened.

But I don't like seeing a lot of locals when I emit KeyboardInterrupt.

Could we let user create some kind of individual rules for some exceptions with mapping like {KeyboardInterrupt: {"show_locals": False}}? It would be great for me.
