Incorporate the ECOMP SDC Artefact Generator code

Remove the Maven dependency on openecomp-sdc-artifact-generator-core,
because this is not maintained in the ONAP source code repositories.
The functionality provided by the SDC Artifact Generator is replaced
with equivalent code that depends on the SDC-TOSCA parsing library,
without introducing any backwards-compatibility breaks.
The intention is to make this Maven project more maintainable by
depending only the common ONAP libraries.
