CSIT-102: Add latency measurement to performance testing
- Add latency stream as a background stream in both directions - Latency background stream is not using the VM transformation engine. Raw stream with single packet is created. - Latency background stream has 1kpps rate with packet of same size as traffic stream. - Display latency values (min/avg/max) in results of TC and reporting remaining data including histogram and jitter inside of the search/pass keyword.
