Add new iocage API call to clone jails.

If you supply props your output will look like this:

REST Request:
-------------------------------
PUT /sysadm/iocage
{
   "props" : "tag=newtest",
   "jail" : "test",
   "action" : "clonejail"
}

WebSocket Request:
-------------------------------
{
   "namespace" : "sysadm",
   "name" : "iocage",
   "args" : {
      "action" : "clonejail",
      "jail" : "test",
      "props" : "tag=newtest"
   },
   "id" : "fooid"
}

Response:
-------------------------------
{
  "args": {
    "clonejail": {
      "jail": "test",
      "props": "tag=newtest",
      "success": {
        "Successfully created": " 5e1fe97e-cfba-11e5-8209-d05099728dbf (newtest)"
      }
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}

Otherwise iocage will populate it's own values and the props returned by the API will be empty:

REST Request:
-------------------------------
PUT /sysadm/iocage
{
   "action" : "clonejail",
   "jail" : "test"
}

WebSocket Request:
-------------------------------
{
   "args" : {
      "jail" : "test",
      "action" : "clonejail"
   },
   "name" : "iocage",
   "namespace" : "sysadm",
   "id" : "fooid"
}

Response:
-------------------------------
{
  "args": {
    "clonejail": {
      "jail": "test",
      "props": "",
      "success": {
        "Successfully created": " 89e78032-cfba-11e5-8209-d05099728dbf (2016-02-09@23"
      }
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}
