Container remapping of HLT jet container names from Run 3 to Run 2 conventions

This allows us to run the unmodified legacy monitoring code on files produced with the AthenaMT trigger configuration, and produce histograms with direct container access. The module can be activated by a preExec when running the physics validation transforms.

I was not able to get the remapping option to work, hence the reliance on overwriting the SG keys entirely. This is discussed in ATR-20001.
