In addition to previous commits about OccupancyMap, we introduce here

In addition to previous commits about OccupancyMap, we introduce here
another OCDB object, the RejectList, which is supposed to span several
runs (ideally a whole running period, e.g one year), and reject
problems that were not seen in the OccupancyMap. At the same time, the
RejectList can be used during reconstruction of simulations to reject
part of the detector on a statistical basis (hence allowing to get
only one efficiency calculation for a whole period).

Besides, note that we removed the ad-hoc cut on DE occupancy in
AliMUONDigitCalibrator, which should now be handled by the occupancy map  and/or the rejectlist.
