Report additional attributes/tags added to configuration

[psrok1]

Currently we can report new artifacts using store-in-karton special key (AFAIK it's not documented enough 🤔) https://github.com/CERT-Polska/karton-config-extractor/blob/master/karton/config_extractor/config_extractor.py#L139.

It would be nice to make possibility for a module to include additional attributes and tags to configuration itself (e.g. if someone wants to include information about extraction rule or specific heuristic that was used to rip configuration)
