[HICN-405] Added application face delete

Added two new messages in the binary api:
- hicn_api_face_cons_del to delete a consumer face
- hicn_api_face_prod_del to delete a producer face

Added the corresponding commands in the vpp_api_test for debugging and testing

Reworked the cache policy structure to add a new function that flash the content store
from the content coming from the destroyed producer face. This is required since the CS
while each producer face has its own lru list. Removing only the producer face without
flushing the CS from the content coming from the producer face will lead to a segfault
in case there is a hit in the CS as the lru no longer exists and it won't be possible
to update the head of the lru.
