Clean up configuration files

Hello @rbielski. I believe this is something you wanted me to do as well. I am a bit unsure on how to handle the "DataObjects" that I kept. Also, not very sure whether I should also remove the line : " # Make sure BCID average still available at whole-event level from AthenaCommon.AlgSequence import AlgSequence topSequence = AlgSequence() topSequence.SGInputLoader.Load += [( 'ILArHVScaleCorr' , 'ConditionStore+LArHVScaleCorrRecomputed' )] " which I am not sure what it is doing. Cheers, Denis
