Add new API call to do the initial setup of Iohyve

Both the pool/nic are required for setup to complete.

REST Request:
-------------------------------
PUT /sysadm/iohyve
{
   "nic" : "re0",
   "pool" : "tank",
   "action" : "setup"
}

WebSocket Request:
-------------------------------
{
   "id" : "fooid",
   "name" : "iohyve",
   "args" : {
      "pool" : "tank",
      "nic" : "re0",
      "action" : "setup"
   },
   "namespace" : "sysadm"
}

Response:
-------------------------------
{
  "args": {
    "setup": {
      "nic": "re0",
      "pool": "tank"
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}
