  """Send dictionary of JSON serializable `values` as a POST body to `url`
     along with `auth_token` that's generated from `secret_key` and `values`

  scheduler.auth.create_token expects a JSON serializable payload, so we send
  a dictionary. On the receiving end of the POST request, the Flask view will
  have access to a werkzeug.datastructures.ImmutableMultiDict. The easiest
  and most surefire way to ensure that the payload sent to create_token will
  be consistent on both ends is to generate an ImmutableMultiDict using the
  werkzeug.Request.
