There should be two possible ways to create a face in a forwarding
strategy: utilizing face manager or directly manipulating face system. To
use face manager for face creation, you can take a look on
tests/daemon/mgmt/face-manager-create-face.t.cpp. The face manager is
designed to allow a different party to alter NFD forwarder states. However,
a forwarding strategy is part of a forwarder, I see no reason why it cannot
manipulate the face system directly. Thus, you could take a look on how
face manager uses face system on face creation, and do similar stuff.
