    Fix os-simple-tenant-usage result order
    
    nova usage-list can return incorrect results, having resources counted
    twice. This only occurs when using the 2.40 microversion or later.
    
    This microversion introduced pagination, which doesn't work properly.
    Nova API will sort the instances using the tenant id and instance uuid,
    but 'os-simple-tenant-usage' will not preserve the order when returning
    the results.
    
    For this reason, subsequent API calls made by the client will use the
    wrong marker (which is supposed to be the last instance id), ending
    up counting the same instances twice.

  This microversion introduced pagination, which doesn't work properly.
  Nova API will sort the instances using the tenant id and instance
  uuid, but 'os-simple-tenant-usage' will not preserve the order when
  returning the results.

  For this reason, subsequent API calls made by the client will use the
  wrong marker (which is supposed to be the last instance id), ending up
  counting the same instances twice.
