updating the VNFD (SOL001) type based on SOL001 v2.5.1

updated VNFD types (tosca*.*nfv.) based on latest v2.5.1 version, not supported backward compatibility of SOL draft version, will be documented as limitation while upgrading from SOL draft version, updated importscript for new nodes, Also fixed java files for policyType having groupType reference
