[HICN-591] Created new command "hicn enable <prefix>" that enable hicn on a given prefix

The changes include:
 - we use now a different vrf for the hicn routes. The default vrf (fib) contains
   every route, we sync the route we marked as hicn on the hicn vrf. In the vrf
   we use a custom dpo to implement the forwarding strategy.
