DDSim: Change Default Output config

[andresailer]

BEGINRELEASENOTES

• DDSim: change the default output file name on how DD4hep was built. Fixes Adjust default output based on compiled format support #1101

  • Add outputConfig.forceLCIO, outputConfig.forceEDM4HEP, outputConfig.forceDD4HEP switches to force a particular output plugin
  • If LCIO was used, slcio is still the default
  • If EDM4hep was used but not LCIO, EDM4hep is the default and used for all root output files.
  • If neither LCIO or EDM4hep was used, then DD4hep's root output is used. Use the outputConfig.forceDD4HEP flag to use DD4hep's root output if EDM4hep is available as well

• DDSim: remove python2 legacy shims

• Geant4UIManager: fail when pre or post run commands are not successfully executed.

Any one has thoughts on "It is no longer possible to use the DD4hep root output of EDM4hep was used for the build."? I am not sure this is a good idea, sometimes probably nice for debugging... But I can't think of a nice and user friendly way at the moment.

I would separate the file name from the output format and have some --lcio --edm4hep --root flags to determine the output format. If none is set, stay for backwards compatibility with the existing functionality.

I know this even adds more flags, but ddsim anyhow lives from flags.

I added some flags (outputConfig.forceLCIO, outputConfig.forceEDM4HEP, outputConfig.forceDD4HEP) to force a given output format.
That should also make the RICH tests pass again.

Thanks @MarkusFrankATcernch
