[dpdk-dev] ip_pipeline: add command for multiple execution of run <file>

  From: Sankar Chokkalingam <sankarx.chokkalingam@intel.com>

The new command enables the execution of script-file for 'n' number of
times in regular intervals. It takes script-file, number of times to be
executed, interval between each execution as inputs.

Syntax: run <file> <count> <interval>

Usage: This command helps to collect statistics of ports and pipelines in
periodic interval.

Example: run port_stats 5 30

The port_stats file may contain the list of port stats commands like
p 1 port in 0 stats
p 1 port out 0 stats
p 2 port in 0 stats
p 2 port out 0 stats
p 2 port in 1 stats
p 2 port out stats.

The list of commands in the file will be executed 5 times with the
interval of 30 seconds.

Hi Jasvinder and Sankar,

This patch is now  reworked and included into the ip_pipeline CLI rework patch set that Michal and Piotr sent: http://www.dpdk.org/ml/archives/dev/2016-May/039429.html

So we can safely discard this patch now.

Thanks,
Cristian
