[dts] [PATCH V1 4/5] framework/pktgen_ixia: measure throughput supports multiple

[yufengmx <yufengx.mo@intel.com>]

 return values

*. remove duration option used in ixia module, move duration option in
   testing scenario methods(latency/loss/throughput) in pktgen_base module.
*. remove un-used parameters in _start_transmission method.
