This orders reusable containers on wish and is meant for scenarios in which a CI does not allow "native" use of reusable test containers but will make sure to clean them up after CI ran. Export a variable `SDN_FORCE_REUSE_OF_CONTAINERS` as `true` and SDN tests won't close the container, regardless whether the underlying Testcontainers supports reuse or not. Closes #2837
