[PATCH v4 11/14] app/graph: add CLI option to enable graph stats

[skori at marvell.com]

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

It 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.
