Title:
  can't add/del parameter in nested stack during stack-update

Status in Orchestration API (Heat):
  New

Bug description:
  Looks like nested stack doesn't allow parameter change. It fails at
              after_props.validate()

  Is it the inention to disable that since update_allowed_properties
  default is none?

  But it's possible to allow that for nested stack, since it's special
  resource constructed by base resource.
