Support importing a VFC with interface implementation extended notataion, e.g.:

node_types:
  org.openecomp.vfcWithInterfaceOpertaionImplExtendedNotation:
    derived_from: tosca.nodes.Root
    interfaces:
      Standard:
        type: tosca.interfaces.node.lifecycle.Standard
        create:
          description: myImportDescription
          implementation:
            primary:
              type: tosca.artifacts.asd.deploymentItem
              file: myFile.yaml
              artifact_version: '1'
              properties:
                artifact_type: mine

Note for property types it is not possible to determine the type for complex types, therefore support for properties shall be limited to types string, integer, float, boolean which will be sufficient for most use cases
