add flag to benchmark runner to activate or deactivate tracking

[twollnik]

add flag to benchmark runner to activate or deactivate tracking. One option: check benchmark runner to see how we can set flags (we need binary flag memory_tracking). this requires changes to the benchmark runner and the benchmark configuration and the cli config parser (see overview below). How to deactivate tracking if we use tracking_vector everywhere: return default memory resource in memory resource manager if tracking is deactivated.
