CLI tool to update/create hardcoded json-ad data from ontologies

[Polleps]

Core classes and properties are defined in code and added to the database during the populate step. It is easy to forget to add these resources to the json files when working on a new feature.

Technically all important resources are defined in the atomicdata.dev ontologies (e.g. core, server, commits, etc.) We could create a script that automatically creates the json files based on these ontologies to make it more easy to update them.
