Code review feedback & back-ground traffic support
Various code review comments taken into account. We also support now background traffic, meaning the scripts will start a test between machines and monitor packet loss, latency, etc., but at the same time, the script will also start traffic on background machines. That traffic will not be monitored. Each generator will generate the same ammoung of traffic. Change-Id: I5cd495be230a526f91de965f3d4dd0581681f5ca Signed-off-by: Luc Provoost <luc.provoost@intel.com>
