Add sipp trafficgen based SampleVNFTrafficGen

This patch defines:
  - Generic VNF APIs to test Network service:
  --> instantiate: prepare the arguments for run sipp
  --> run_traffic: run sipp test and handle the result file
  --> collect_kpi: collect results and push to queue
  --> terminate

JIRA: YARDSTICK-1446
