fib: Add fib rule match on tunnel id
This add the ability to select a routing table based on the tunnel id which allows to maintain separate routing tables for each virtual tunnel network. ip rule add from all tunnel-id 100 lookup 100 ip rule add from all tunnel-id 200 lookup 200 A new static key controls the collection of metadata at tunnel level upon demand.
