yardstick: CLI params support for yardstick TCs
Vswitchperf specific class in yardstick was updated to reflect new functionality of --test-params. These changes have impact on vsperf documentation and yardstick samples. As part of this fix following changes were made: * trafficgen mode can be executed with default configuration * yardstick specific TC samples were updated * dummy traffic generator was enhanced to support back2back * dummy traffic generator was enhanced to accept traffic results from configuration JIRA: VSPERF-422 JIRA: VSPERF-205 Change-Id: Ibeaa6ef46bde453e3ca5dee6e4568fc8c3853521 Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Bill Michalowski <bmichalo@redhat.com> Reviewed-by: Antonio Fischetti <antonio.fischetti@intel.com> Reviewed-by: <sridhar.rao@spirent.com>
