Satheesh Paul fda3750de6 app/flow-perf: add random priority option
Added support to create flows with priority attribute set
randomly between 0 and a user supplied maximum value. This
is useful to measure performance on NICs which may have to
rearrange flows to honor flow priority.

Removed the lower limit of 100000 flows per batch.
