Rate doesnt work properly #2

When rate is specified as 3000 and len is specified as 10, the tool should send 3000 packets per second (or max possible) for 10 seconds. The average QPS and Latency should be printed to STDOUT once every second.

However, below is the output.

2019/11/03 18:07:29 QPS:  3000  Latency:  330.396µs
2019/11/03 18:07:32 QPS:  3000  Latency:  329.141µs

If 3000 queries cannot be achieved in 1 second, the tool sends 3000 queries (takes more than a second) and prints the output. The tool runs for 10 seconds and exits, printing output at only 4 intervals instead of 10.
