Add two new API calls, to shutdown/halt the system, and to

reboot the system.

Shutdown API call

REST Request:
-------------------------------
PUT /sysadm/systemmanager
{
   "action" : "halt"
}

WebSocket Request:
-------------------------------
{
   "id" : "fooid",
   "args" : {
      "action" : "halt"
   },
   "name" : "systemmanager",
   "namespace" : "sysadm"
}

Response:
-------------------------------
{
  "args": {
    "halt": {
      "response": "true"
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}

Reboot API call

REST Request:
-------------------------------
PUT /sysadm/systemmanager
{
   "action" : "reboot"
}

WebSocket Request:
-------------------------------
{
   "id" : "fooid",
   "args" : {
      "action" : "reboot"
   },
   "name" : "systemmanager",
   "namespace" : "sysadm"
}

Response:
-------------------------------
{
  "args": {
    "reboot": {
      "response": "true"
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}
