If the flaky plugin for pytest is available, use its decorator to support re-running unstable tests. In case the package is missing, execute the test as usual without attempts to re-run it in case of failure. This is mostly intended to increase the test stability in CI. Using a custom decorator enables us to keep the flaky package as an optional dependency.
