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.
