logilab-devtools #80762 make "lgp setup -q" be really quiet [resolved]

"lgp setup -q" should set the log level threshold at ERROR instead of WARNING, so it is really quiet but there are real problems (aka errors).

The reason why I am asking this is that I do not want to see my "lgp setup -q" cron jobs report me each and every day that W: /.pbuilderrc does not exist
