Add console handler for logging

[niksirbi]

Our current logging configuration only adds a rotating file handler, and does not configure a console handler. This means:

• All log messages at the DEBUG level and above are written to the log file.
• No log messages are output to the console.

What we would actually want:

• INFO, WARNING, and ERROR messages should be printed both to the log file and the console.
• DEBUG messages should be written only to the log file.

To achieve this behaviour, we need to add a console handler to our logger and set the appropriate log levels for both handlers.

We could also use loguru or fancylog to reduce the amount of logging configuration we have to do on our side.

If we go with fancylog, we'd have to first address this issue.

naive question:

is it a matter of adding a

import logging
logging.getLogger().setLevel(logging.INFO)

?

EDIT: we confirm this was indeed naive 😬
