[dts] [Patch V1] framework/tester.py : add this function to support ixia to send fixed number of packets during certain period it is only for test_suite nic_single_core_perf, not for common use

[Liu, Yong]

Fei,
Please make sure your code align to pep style.
I still has question for parameter "runTime", this value is depend on rate, total number and link rate.
I think the only value for this parameter is to make sure all packets transmitted.
Why not just check how many packets emitted and return when equal to parameter "packetNum".

Thanks,
Marvin
