[v11,11/12] app/graph: support CLI option to enable graph stats

  From: Sunil Kumar Kori <skori@marvell.com>

Adds application's command line parameter "--enable-graph-stats"
to enable dumping graph stats on console.

By default, no graph stats will be printed on console but same can
be dumped via telnet session using "graph stats show" command.
