Draft: Shorten console output of pytest to avoid overflow of gitlab log

In the long scheduled pytest jobs, the number of characters to be displayed by gitlab is reached and the console log stops. The final summary about failures/passes is not visible anymore because of that. My proposal would be to remove the -v flag and have the less verbose output to avoid that. The final summary reveals the names of the testcases for local reproduction and the direct command lines can be obtained from the report in the artifacts.
