[HICN-590] Removed andjacency type specific face implementation
Changes in the new implementation are:
- the adjacency index is replaced with a dpo that allows the single face node
to dispatch the packet to the right vlib node.
- local and remote address in the face are replaced with a single nat address
which is used to perform the nat operation when rewriting an interest or a
data (in case of tunnels the nat address will be equal to 0)
- the list of next hop in the load balance is no longer a list of dpos but
a list of face id (this makes the code easier and increases the number of
next hop we supports)
