Turn on quiet mode when logfile specified

Browse Source 
I'm not really sure why I originally had --logfile also log to stdout
in I202e1cb200bde17f6d7770cf1e2710bbf4cca64c, but it seem
counter-intuitive (indeed, I just tripped myself up thinking that in a
devstack job "--logfile" would put the logs into a separate file and
avoid the stdout logging, and I wrote it!).

Make it so specifying a --logfile puts dib into quiet mode for stdout.
Explicitly overriding DIB_QUIET will allow both if someone wants that.

Setting ``--logfile`` will now imply ``DIB_QUIET=1`` (i.e. logs will
not appear on stdout). You can override this with an explicit
``DIB_QUIET=0`` if you want stdout and file logging.
