The main if not only use case for per-queue stats today is checking
for traffic imbalance. Add simple traffic balance analysis to qstats.
$ ynltool qstat balance
eth0 rx 44 queues:
rx-packets : cv=6.9% ns=24.2% stddev=512006493
min=6278921110 max=8011570575 mean=7437054644
rx-bytes : cv=6.9% ns=24.1% stddev=759670503060
