[ndnSIM] Calculate Hit Rate from Spesific Nodes in NFD Content Store

[Junxiao Shi]

Hi Adi

NFD already has CS hit/miss counters:

1. Get a hold of Forwarder instance.
2. Read the counter with forwarder.getCounters().nCsHits and
forwarder.getCounters().nCsMisses.

There’s no need to modify any callbacks.

Yours, Junxiao
