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

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"
          }
        }
      }
    }
