feat(logs): Make the logging integration send Sentry logs

[colin-sentry]

We have integrations that make the python logger create breadcrumbs and issues. This adds a third handler which creates Sentry logs on logger.log statements.

Enable the logger with:

sentry_sdk.init(
    ...
    _experiments={
        "enable_sentry_logs": True
    }
)

some_logger = logging.Logger("some-logger")
some_logger.info('Finished sending answer! #chunks=%s', chunks)

Refs #4150

All in all looks good. I have some questions

[antonpirker]

@colin-sentry I have moved the new parameter sentry_logs_level to the end of the parameter list, so we do not break peoples setup if they use positional parameters.

[antonpirker]

This looks good now. 🔥
