add infrastructure and demonstrator-code for AODFix in CA-based jobs
Introduce AODFix for ComponentAccumulator jobs.
The files AODFixConfig.py
and AODFixHelper.py
contains the AOD-Fix infrastructure. This is now called from PoolReadConfig.py in case of AOD-reading.
The remaining files are part of a demonstrator that does nothing useful.
