MunoConfig: Python code fixes for new style config
Python code fixes for new muon configuration modules. Some style fixes but also real bugs.
cc @emoyse: there are still a few remaining problems that needs an expert to look at. Please run flake8 --select ATL,F,E7,E9,W6 MuonSpectrometer/MuonConfig/python/MuonSegmentFindingConfig.py
and provide some fixes. Thanks!
