Polish up logging

[janbuchar]

In the current state, we make a new logger in every module that needs to log something. There is CrawleeLogFormatter, which handles logging in the console.

• our loggers should default to the "info" level
• ??? the log format for Apify platform may be different (doesn't it ingest JSON? probably not, but I'm not sure)
• in JS Crawlee, some classes accept loggers instead of creating them - we may want to revisit that
• printing extra key-value information should now be possible via kwargs of logging.info and related methods - should we use that?

Also, a question that comes to mind: do we want to override the default Python logger formatting? considering Crawlee is a library

And also a framework... It is not unusual for frameworks to define their own loggers. But if a client wants to override that, we should make it easy.
