can't configure logging level for kubernetes observer

[stephane-additive]

Bug summary

We have some issues with our prefect worker's kubernetes observer, and we're trying to narrow down where the issue comes from. In order to do that, we'd like to enable debug logging for all the logs in observer.py, but it looks like it's being hardcoded to logging.INFO in that same file, instead of being left to logging.yml.

Is there any chance we could move the logger configuration back to logging.yml, and remove all python-forced level setting?
