GET /api/1.3/cdns returns wrong response code and response format when unauthorized or forbidden

[mitchell852]

If you try to access GET /api/1.3/cdns without being logged in (i.e. no valid cookie) the response should look like this:

401 Unauthorized

{
alerts: [
{
level: "error",
text: "Unauthorized, please log in."
}
]
}

If you are authenticated (your login cookie is valid) but your user doesn't have the proper priv level, the response should look like this:

403 Forbidden

{
alerts: [
{
level: "error",
text: "Forbidden."
}
]
}
