Data Stage connector capability to process virtual assets

[lpalashevski]

Following requirements were discussed on the virtual Egeria workshop:

• If the option "includeVirtualAssets" is set to true, the connector will send the virtual assets information through (via new DataEngine api calls);
• In case of mode=JOB_LEVEL, it includes: database schema (deployed database schema as asset in egeria), relational tables;
• Data files are still under discussion because of the way they are used in IGC (file patterns and not file instances). We need to decide what will be the correct type used in Egeria (DataFolder?);
• Connection level metadata is not useful and we are not going to create Egeria representation;
• Data Engine can then do lineage mappings using the assets created from virtual IGC assets.
