Work out to show DEBUG level messages emitted early in kedro process

[antonymilne]

Currently any DEBUG level messages emitted by logging calls before session._setup_logging will never be shown, even if you alter your project logging.yml to show DEBUG level messages. This is because framework-side logging sets kedro logging info to level INFO (which is the right default, we shouldn't change that to DEBUG). This isn't a big deal but would be nice if users had a way to show the messages if they want.

Options:

• preferred: Make framework-side logging.yml user-specifiable #2206
• some sort of a verbosity flag to change logging level (note we already have a verbosity option on some commands, but it looks like it only changes how detailed KedroCliError message is) e.g. https://hydra.cc/docs/tutorials/basic/running_your_app/logging/

This will be fixed by #2206 since you'll then be able to specify DEBUG as a level when framework logging config is used.
