Statistics for e2e app

[JohannesDoberer]

We have no statistics how many test coverage we have for our e2e test app. -> show statistics for e2e test coverage

Ideal we also can combine statistics of unit and e2e test coverage. -> investigate if the combination of both is possible.

All the logic that generates the report is ready. The problem is that the stats are only generated for the e2e folder and not for the core. From what I was able to find on the internet, this solution can be in the files that are includes and excludes in the nyc configuration. But I try it and still I don't have any working solution.

de-prioritized, maybe can be revisited later, closing for now
