Description

I was testing Brooklyn HA and noticed something odd: when restarting an HA Brooklyn node, it changes it's node ID reported by `/v1/server/ha/states`.

For instance, I have 2 Brooklyn nodes, 1 master, 1 slave. I stopped master (not killed, stopped), slave took over as expected. Then I restarted the previous master, it came back online as a slave (expected) but the node ID was different. I was expecting it to keep its ID rather creating a new one.

{
  "planeId": "qDpn2Lau",
  "ownId": "nJagUrw8",
  "masterId": "nJagUrw8",
  "nodes": {
    "BgOjYcml": {
      "nodeId": "BgOjYcml",
      "nodeUri": null,
      "status": "TERMINATED",
      "localTimestamp": 1510052259169,
      "remoteTimestamp": 1510052260000
    },
    "iv3XfaEu": {
      "nodeId": "iv3XfaEu",
      "nodeUri": null,
      "status": "STANDBY",
      "localTimestamp": 1510054973636,
      "remoteTimestamp": 1510054974000
    },
    "nJagUrw8": {
      "nodeId": "nJagUrw8",
      "nodeUri": null,
      "status": "MASTER",
      "localTimestamp": 1510054975025,
      "remoteTimestamp": 1510054976000
    }
  },
  "links": {}
}

On the JSON above, BgOjYcml is the same node as iv3XfaEu but BgOjYcml was the ID of the node before restart.
