[ndnSIM] List all Installed Prefix on a Node from App

[Hitesh Wadekar]

Thank you Alex.

It worked, however, I will prefer to use aggregation object on node for
prefix through AppHelper. It will help to track and get the application
based configured prefix as we can configure many applications on same node.

Cheer,
Hitesh
