zebra: fix JSON fields for "show ip/ipv6 nht"

Browse Source 
1. Renamed "gates" to "nexthops"
2. Displaying afi of the nexthops being dispalyed in place of
   "nexthops" JSON object in the old JSON output
3. Calling show_route_nexthop_helper() and show_nexthop_json_helper()
   instead of print_nh() inorder to keeps the fields in "nexthops"
   JSON object in sync with "nexthops" JSON object of
   "show nexthop-group rib json".

Updated vtysh:
    r1# show ip nht
    192.168.0.2
     resolved via connected
     is directly connected, r1-eth0 (vrf default)
     Client list: static(fd 28)
    192.168.0.4
     resolved via connected
     is directly connected, r1-eth0 (vrf default)
     Client list: static(fd 28)

Updated JSON:
    r1# show ip nht json
    {
      "default":{
        "ipv4":{
          "192.168.0.2":{
            "nhtConnected":false,
            "clientList":[
              {
                "protocol":"static",
                "socket":28,
                "protocolFiltered":"none"
              }
            ],
            "nexthops":[
              {
                "flags":3,
                "fib":true,
                "directlyConnected":true,
                "interfaceIndex":2,
                "interfaceName":"r1-eth0",
                "vrf":"default",
                "active":true
              }
            ],
            "resolvedProtocol":"connected"
          }
        }
      }
    }
