CLI —verbose support

[oscar60310]

What’s the problem you're trying to solve

We haven't had a proper way to set log levels and control what components to show (e.g. file path, function name ...etc.)

Describe the solution you’d like

Provide a global flag for CLI --verbose, -v. Set the log level to silly or debug and show file paths and function names, otherwise set the log level to info and hide file paths and function names.
