Add GitHub Actions workflow for E2E tests

Run tests for read-only and read-write mode in parallel across
multiple Kubernetes versions.

Upload artifacts (logs, screen recordings) in case of failure.

Changes to the test script are backwards compatible so existing
use such as the nightly s390x / ppc64le tests on dogfooding continue
to work as expected.
