Title:
  Incompatible version response

Status in OpenStack Identity (Keystone):
  Fix Released

Bug description:
  
  The XML response for the versions request (GET /) changed in Grizzly so that clients that worked with Folsom don't work with Grizzly.
  Specifically, the link to the "stable" endpoint in Folsom is in the versions/version/link element, whereas in Grizzly it's under versions/version/links/link (there's an extra links container).

  The Keystone server's response to a versions request on Grizzly should
  be compatible with the response in Folsom so that a client that worked
  with Folsom will work with Grizzly.

  One way to fix this is to also include the link elements directly
  under the version elements. This way clients that are used to the
  current behavior will continue to work and clients that worked with
  Folsom will now work.

  To recreate, use devstack. 'curl -H "Accept: application/xml"
  http://localhost:5000' with a Folsom devstack and the same with a
  Grizzly devstack.

  BTW - I tried with application/json media-type and the response looks
  compatible, so it's just XML that's affected.

  Here's the results from my system:

  Folsom:

  $ curl -H "Accept: application/xml" http://localhost:5000
  <?xml version="1.0" encoding="UTF-8"?>
