Add API call to start the iohyve installation of a guest from

an ISO

FYI, this only boots the VM with the ISO, to do the install
the user still needs to run "iohyve console <name>" from the system,
which uses serial mode to bring up a terminal

REST Request:
-------------------------------
PUT /sysadm/iohyve
{
   "name" : "bsdguest",
   "iso" : "FreeBSD-10.2-RELEASE-amd64-disc1.iso",
   "action" : "install"
}

WebSocket Request:
-------------------------------
{
   "namespace" : "sysadm",
   "name" : "iohyve",
   "id" : "fooid",
   "args" : {
      "action" : "install",
      "iso" : "FreeBSD-10.2-RELEASE-amd64-disc1.iso",
      "name" : "bsdguest"
   }
}

Response:
-------------------------------
{
  "args": {
    "install": {
      "iso": "FreeBSD-10.2-RELEASE-amd64-disc1.iso",
      "name": "bsdguest"
    }
