Properties are not inherited from super- to sub-node types

[Vahid Hashemian]

Example:

The node type "SoftwareComponent" has a "component_version" property.
The custom type "Collectd" (as used in tosca_elk.yaml) inherits from "SoftwareComponent" node type.
So, one would expect to be able to use the "component_version" property for "Collectd" node type.
However, this would lead to UnknownFieldError exception by parser:
  Properties of template app_collectd contain(s) unknown field: "component version", refer ...

This is the template used:
