[Yardstick-233]latency measurment by using pktgen-dpdk
VM A runs pktgen-dpdk as a traffic generator and is connected
back-to-back with VM B running testpmd for forwarding packets.
1. use linux expect to fetch the latency statics data.
2. fetch 10 samples of latency and calculate avg_latency.
3. use screen to keep test scripts running in the background.
4. add a function send_command() for screen in ssh.py
