Add a new iocage API call to activate zpools.

It has 2 different outputs depending on if `pool` was actually specified.

If you specify a pool this is what you get:
REST Request:
-------------------------------
PUT /sysadm/iocage
{
   "action" : "activatepool",
   "pool" : "tank"
}

REST Response:
-------------------------------
{
    "args": {
        "activatepool": {
            "success": "pool tank activated."
        }
    }
}

WebSocket Request:
-------------------------------
{
   "args" : {
      "action" : "activatepool",
      "pool" : "tank"
   },
   "name" : "iocage",
   "id" : "fooid",
   "namespace" : "sysadm"
}

WebSocket Response:
-------------------------------
{
  "args": {
    "activatepool": {
      "success": "pool tank activated."
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}

If you do not specify a pool, this is your output:
REST Request:
-------------------------------
PUT /sysadm/iocage
{
   "action" : "activatepool"
}

REST Response:
-------------------------------
{
    "args": {
        "activatepool": {
            "currently active": {
                "pool": " tank"
            }
        }
    }
}

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

WebSocket Response:
-------------------------------
{
  "args": {
    "activatepool": {
      "currently active": {
        "pool": " tank"
      }
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}
