Subject: [PATCH] Add new API call to fetch an ISO for iohyve

Uses the "url" argument, which should be the address understood by "fetch" to
grab an ISO from, I.E. http://, ftp://, file://, etc

The task will queue, and return an event when finished

REST Request:
-------------------------------
PUT /sysadm/iohyve
{
   "url" : "ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/ISO-IMAGES/10.1/FreeBSD-10.1-RELEASE-amd64-disc1.iso",
   "action" : "fetchiso"
}

WebSocket Request:
-------------------------------
{
   "namespace" : "sysadm",
   "name" : "iohyve",
   "args" : {
      "url" : "ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/ISO-IMAGES/10.1/FreeBSD-10.1-RELEASE-amd64-disc1.iso",
      "action" : "fetchiso"
   },
   "id" : "fooid"
}

Response:
-------------------------------
{
  "args": {
    "fetchiso": {
      "command": "iohyve fetch ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/ISO-IMAGES/10.1/FreeBSD-10.1-RELEASE-amd64-disc1.iso",
      "comment": "Task Queued",
      "queueid": "{b3a8b980-a564-4ff8-86a2-1971bd4f58d1}"
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}
