make the e2e feature tests run as a parallel test by default

Now the e2e feature tests took too much time together to finish execution, so
instead of sequentially executing the tests the CI will execute them in a parallel way.

Optionally in a followup change, the separate parallel job definitions could
be removed, because with this current change all e2e feature tests will run as parallel tests.
