Add a simple performance test that sends a continuous stream

Implement a simple performance test that sends a continuous
stream of traffic to the vSwitch at line rate for 30 seconds
and measures the throughput
Note: there is issue with calculating of the Tx Fps and Mbps
based on the results from the IxNetwork traffic generator.
This issue will be fixed in a later patch.
