CI Logs

[mato533]

Description

The current CI shows E2E logs only logs for GitHub Actions.
But E2E scenarios have increased, which makes it harder to find some of the necessary information for investigating failures.

The suggestion is to put the log files into a ZIP file and upload them as artefacts, which developer can then download later.

Concerns from a different perspective (it may be better to separate Issues.)

It might be a good idea to change the E2E logging levels and clarify how the different logging levels are used in the first place (especially Debug and Trace).

e.g..
Debug: information to enable tracing of the execution state of the normal system
Trace: all information needed for investigation (e.g. log information on intentionally caused errors)
