Description

Add two counters to ForwarderStatus's GeneralStatus dataset:

number of satisfied Interests, incremented when a PIT entry that has been satisfied is being removed
number of unsatisfied Interests, incremented when a PIT entry that has not been satisfied is being removed

These are global forwarder counters, not per-face counters.

Beichuan asked for this feature during the 2018-08-20 NDN Platform call.

The definition of "unsatisfied Interest" needs to be clarified. Does it include currently pending Interests or not? Does it include Nacked Interests or only timeouts?
