    Fix logging to stdout and file in classes/commands

    Fix logging to console to depend on input CLI args. By default, keep
    logging to stdout. Make --log-file argument working as well.

    Use the input verbosity parameters as a controlling switch for
    logs verbosity.

    Evaluate log levels as:

      * 1 (WARNING+) - the default log level if neither -v nor --debug used
      * 2 (INFO+) - applies if -v / --verbose
      * 4 (DEBUG+) - applies if --debug, dumps command results to file,
        if --log-file is requested.
      * 5 (DEBUG+) - applies if --debug and -v. Like the latter mode, but
        also dumps the executed commands results to console.

    This is needed for better deployments troubleshootng.
