trigger after Interest is received

The Interest:

The strategy should decide whether and where to forward this Interest.

If the strategy decides to forward this Interest, invoke this->sendInterest one or more times, either now or shortly after
If strategy concludes that this Interest cannot be forwarded, invoke this->rejectPendingInterest so that PIT entry will be deleted shortly

Warning: The strategy must not retain shared_ptr<pit::Entry>, otherwise undefined behavior may occur. However, the strategy is allowed to store weak_ptr<pit::Entry>.
