Add nexthop subcommand to ip. Implement basic commands for creating,
deleting and dumping nexthop objects. Syntax follows 'nexthop' syntax
from existing 'ip route' command.
Examples:
1. Single path
$ ip nexthop add id 1 via 10.99.1.2 dev veth1
$ ip nexthop ls
id 1 via 10.99.1.2 src 10.99.1.1 dev veth1 scope link
2. ECMP
$ ip nexthop add id 2 via 10.99.3.2 dev veth3
$ ip nexthop add id 1001 group 1/2
--> creates a nexthop group with 2 component nexthops:
id 1 and id 2 both the same weight
$ ip nexthop ls
id 1 via 10.99.1.2 src 10.99.1.1 dev veth1 scope link
id 2 via 10.99.3.2 src 10.99.3.1 dev veth3 scope link
id 1001 group 1/2
3. Weighted multipath
$ ip nexthop add id 1002 group 1,10/2,20
--> creates a nexthop group with 2 component nexthops:
id 1 with a weight of 10 and id 2 with a weight of 20
$ ip nexthop ls
id 1 via 10.99.1.2 src 10.99.1.1 dev veth1 scope link
id 2 via 10.99.3.2 src 10.99.3.1 dev veth3 scope link
id 1001 group 1/2
id 1002 group 1,10/2,20
