Ido Schimmel 2be6d18b30 nexthop: Add support for nexthop buckets 
Add ability to dump multiple nexthop buckets and get a specific one.
Example:

 # ip nexthop add id 10 group 1/2 type resilient buckets 8
 # ip nexthop
 id 1 via 192.0.2.2 dev dummy10 scope link
 id 2 via 192.0.2.19 dev dummy20 scope link
 id 10 group 1/2 type resilient buckets 8 idle_timer 120 unbalanced_timer 0 unbalanced_time 0
 # ip nexthop bucket
 id 10 index 0 idle_time 28.1 nhid 2
 id 10 index 1 idle_time 28.1 nhid 2
 id 10 index 2 idle_time 28.1 nhid 2
 id 10 index 3 idle_time 28.1 nhid 2
 id 10 index 4 idle_time 28.1 nhid 1
 id 10 index 5 idle_time 28.1 nhid 1
 id 10 index 6 idle_time 28.1 nhid 1
 id 10 index 7 idle_time 28.1 nhid 1
 # ip nexthop bucket show nhid 1
 id 10 index 4 idle_time 53.59 nhid 1
 id 10 index 5 idle_time 53.59 nhid 1
 id 10 index 6 idle_time 53.59 nhid 1
 id 10 index 7 idle_time 53.59 nhid 1
 # ip nexthop bucket get id 10 index 5
 id 10 index 5 idle_time 81 nhid 1
 # ip -j -p nexthop bucket get id 10 index 5

Ido Schimmel b82d6b81fa nexthop: Add ability to specify group type 
Next patches are going to add a 'resilient' nexthop group type, so allow
users to specify the type using the 'type' argument. Currently, only
'mpath' type is supported.

These two commands are equivalent:

 # ip nexthop add id 10 group 1/2/3
 # ip nexthop add id 10 group 1/2/3 type mpath
