Title:
  [heat] certain template errors display a long stack trace in the red
  error popup

Status in Orchestration API (Heat):
  New

Bug description:
  I have found that certain types of template errors are not caught in
  the first validation pass, and instead fail in the second phase, when
  all the parameters are submitted.

  For example, adding an invalid property to an output does this. Here
  is an example (only showing the "outputs" section):

  outputs:
    mysql_instance_name:
      description: Name of the MySQL instance
      value: { get_attr: [mysql_instance, name] }
    mysql_instance_ip:
      description: The IP address of the MySQL instance
      value: { get_attr: [mysql_instance, first_address] }
    mysql_password:
      description: The MySQL root password
      value: { get_attr: [mysql_password, value] }
      hidden: true

  The "hidden" parameter is invalid for an output, but the initial
  template validation does not find an error (likely a Heat problem).
  When the template is finally submitted a stack trace appears in the
  red popup error (see attached screenshot).
