ip route: Add support for vrf keyword
Add vrf keyword to 'ip route' commands. Allows:
1. Users can list routes by VRF name:
$ ip route show vrf NAME
VRF tables have all routes including local and broadcast routes.
The VRF keyword filters LOCAL and BROADCAST routes; to see all
routes the table option can be used. Or to see local routes only
for a VRF:
$ ip route show vrf NAME type local
2. Add or delete a route for a VRF:
$ ip route {add|delete} vrf NAME <route spec>
3. Do a route lookup for a VRF:
$ ip route get vrf NAME ADDRESS
