Merged requested to merge emoyse/athena:master-fix-muonconfig into master
MuonConfig was started before we had any central handling of arguments etc in CA
This MR removes some now unneeded code, and moves to use
fillFromArgs more consistently.
Tested with unit tests of affected packages.
Keeping as Draft until someone (@jojungge?) can tell me how to test the
DerivationFrameworkHiggs changes (
python -m DerivationFrameworkHiggs.FourLeptonVertexing --threads=1 did not work).
