[c-nsp] Per session shaping

[adi.siswanto]

Hi Steve,
if you put DPI between LAC - LNS, I think it will difficult for DPI to
recognize per user traffic, because it inside tunnel (cmiiw). The common
implementation is to put DPI after LNS.
For per user traffic shaping you can use radius attribut on the LNS, you
can see below
