          ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD
          based on TOSCA specifications.
          VNF configurable properties are sometimes also referred to as
          configuration parameters applicable to a VNF. Some of these are set
          prior to instantiation and cannot be modified if the VNF is
          instantiated, some are set prior to instantiation (are part of
          initial configuration) and can be modified later, and others can be
          set only after instantiation. The applicability of certain
          configuration may depend on the VNF and the required operation of
          the VNF at a certain point in time.
          These configurable properties include the following standard
          attributes, which are declared in the VNFD if auto-scaling and/or
          auto-healing are supported by the VNF: 
          * isAutoscaleEnabled: If present, the VNF supports auto-scaling. If
            set to true, auto-scaling is currently enabled. If set to false,
            auto-scaling is currently disabled. 
          * isAutohealEnabled: If present, the VNF supports auto-healing. If
            set to true, auto-healing is currently enabled. If set to false,
            auto-healing is currently disabled.
