placement: Version discovery URI should not require authentication

[Eric Fried]

The placement API GET / returns the version document:

 <Response [200]>
 {
   "versions": [
     {
       "min_version": "1.0",
       "max_version": "1.10",
       "id": "v1.0"
     }
   ]
 }

However, it requires authentication:

# curl http://9.1.2.3/placement/
{"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}

It shouldn't. Right now I can't find the doc that says so, but Monty confirms:

    placement: skip authentication on root URI

    The placement API GET / is for version discovery. Skip authentication
    on this URL.

    The change to test_deploy is required to make it request a URL that
    requires authentication. It had been using /.
