LHCBSCIFI-9: Remove plotting methods from digitisation algorithms [https://its.cern.ch/jira/browse/LHCBSCIFI-9]
For MCFTDepositCreator, MCFTDigitCreator and FTClusterCreator:
- moved plots to monitoring whenever possible.
- added configurable (default=off) to add plots for intermediate calculations in the algorithms
- commented out plots when I was doubtful if they were necessary
- general cleanup of plots
Still needs a review to assess what plots we do and do not need.
