Align cpg-concepts with cloud-property-graph repo

[oxisto]

In the long run, we want to include / align the concepts here with the functionalities / security features we have in https://github.com/clouditor/cloud-property-graph. This will have the advantage the we are more in sync with regards to the development, because currently the CloudPG repo is lagging behind (main is still on CPGv6).

This poses several challenges, which will probably be dedicates issues

• Can/should be leverage the concepts out of the cloud ontology? Can we auto-generate them here as Concept nodes?
• Do we want/need the class hierarchy we have currently in the CloudPG, probably yes
• Where do we want to place the passes that fill the concept with framework specific stuff. There might be a lot of them, for different languages, so we need to organise
• Can we have something "smarter" than the current pass system? Something like a DSL that is more suitable to quickly extend for new frameworks?
