Increase min_rate for NDRPDR tests
Latency measurements break for loads less than 9 kpps per direction. Setting min_rate to 90 kpps prevents 10% latency trial from breaking. 90 kpps should be enough for any type of test. When some test finds a lower value, this patch will make the fail with a message saying the loss rate at minimal load is too high (instead of a cryptic error from 10% measurement without this patch).
