Use logging levelno instead of levelname. Levelnames can be overridden

See #1443

Great PR @rrauenza !

Please add tests that change the level name of all levels and test for _logging_to_event_level returning the correct event level name here:
https://github.com/getsentry/sentry-python/blob/master/tests/integrations/logging/test_logging.py

If we have all those little changes, I think we are good to go!
Thanks!

not set ... I'm not sure how to test that, so that line is commented out.

Ah, I see:

I'm not sure sentry will see this case...

Hey @rrauenza !

Thanks for the update!
I did some minor changes in your branch, but I think now everything looks good!

[antonpirker]

@sl0thentr0py could you please have a look at this?

[antonpirker]

Hey @rrauenza !
If the tests are all green, we are ready to merge this!

Thanks for this contribution, really great!

If you send me your shipping address to anton (dot) pirker [at] sentry {dot} io I can send you a couple of stickers as a small token of appreciation!
