• [x] introduce template data resolver in commons (for SecHub server, PDS side and also wrpapers)
• [x] create and add PDS parameter pds.config.template.metadata.list which contains information about assets for template types and also variable data
• [x] an integration ensures that the PDS will receive pds.config.template.metadata.list parameter
• [x] ensure asset available for PDS jobs (upload in asset storage if not already there, or if checksum is not as expected - as a fallback for a db restore or storage problems)
