Agent service address field only visible for local services

[sttts]

The address field – introduced in #570 – is only correctly returned via the API for services on the local host.

As an example I have three mongo instances on three different hosts (each running a consul server instance). On each host I get a different picture from /v1/agent/services:

[
  {
    "Port": 27017,
    "Address": "",
    "Tags": [
      "tweventy"
    ],
    "Service": "mongo",
    "ID": "master2:mesos-7095bd12-e725-41cf-a664-28d0b5e8ffca:27017"
  },
  {
    "Port": 27017,
    "Address": "10.2.0.9",
    "Tags": [
      "tweventy"
    ],
    "Service": "mongo",
    "ID": "master2:mesos-8527777f-3fa7-4602-b0b5-a844698c3881:27017"
  },
  {
    "Port": 27017,
    "Address": "",
    "Tags": [
      "tweventy"
    ],
    "Service": "mongo",
    "ID": "master2:mesos-883a2b28-a82f-43a5-b625-08a544d9f817:27017"
  }
]

On host1 only the service on host1 has a filled address field, on host2 only the service on host2 and so on.

False alarm.
