API CHANGE: last sysadm/firewall action

Final action for the sysadm/firewall class: "action" = "reset-defaults"
This will reset all the firewall settings back to defaults and restart the firewall.
NOTE: This will only work on TrueOS - plain FreeBSD does not have any concept of default firewall settings and this API call will return an error in that case.

REST Request (example):
-------------------------------
PUT /sysadm/firewall
{
   "action" : "reset-defaults"
}

WebSocket Request:
-------------------------------
{
   "id" : "fooid",
   "args" : {
      "action" : "reset-defaults"
   },
   "namespace" : "sysadm",
   "name" : "firewall"
}

Response:
-------------------------------
{
  "args": {
    "result": "success"
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}
