[API CHANGE]

Add a new API call to the sysadm/users framework as well as add a bunch more output to current users requests (error/success reporting instead of just the overall good/bad flag).

New API call: "action":"userdelete"
REQUIRED: "name":<username>
OPTIONAL: "clean_home"="true/false" (default is "true")

REST Request (example):
-------------------------------
PUT /sysadm/users
{
   "name" : "test",
   "action" : "userdelete"
}

WebSocket Request:
-------------------------------
{
   "id" : "fooid",
   "name" : "users",
   "args" : {
      "action" : "userdelete",
      "name" : "test"
   },
   "namespace" : "sysadm"
}

Response:
-------------------------------
{
  "args": {
    "result": "success"
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}
