bitbake: knotty: Colorize knotty interactive console output

Add bold color output to log level name and standard color output to log msg
when bitbake is run from an iteractive console.  Color output is only
enabled
if the terminal supports color.

Used Jason Wessel's recommendation for transparency on verbose, note and
plain.
