[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)
