  Template for scaling which targets is not set in tosca.policies.nfv.VduScalingAspectDeltas.
  The following nodes are not set in hot.
  ->OS::Heat::AutoScalingGroup
  And create empty <aspect_name>.yaml.
  In Addition, the following properties are not set in
  <aspect_name>_scale_in and <aspect_name>_scale_out nodes.
  ->scaling_adjustment
