In several KVM tests, it is very useful to log commands sent
to the monitor and their responses, but most of the time
output from such commands in verify_responsive and screendump
threads are not necessary. So, introduce the param debug in
monitor.cmd(), that defaults to True, and then later turn
off selectively outputs from the parts of the framework
where monitor commands are excessively called and their
output is not so interesting.
