not sure when this was implemented, but it's already possible in qtests

> From time to time I get back to a scenario where I want to investigate a compaction related issue and I have a complete repro SQL script for that. In this case, I would prefer a qtest in which I can run manually triggered compaction instead of setting up other kinds of unit tests.
> This can be quite challenging, but the most important is that a compactor environment (compactor threads, queue, etc.) cannot be set on the fly in the scripts. Fortunately, we already have some preprocessed meta stuff in qtest which can run in advance, it worth try that for this purpose.
