ATR-27964 Support removed TriggerTowers with zero energy in MC L1Calo sim
This MR is meant to solve ATR-27964. Warning are popping up because we are running on MC instead of Data. The TriggerTowers are done using the Run2TriggerTowerMakerCfg and it removes all Towers with et=0 energy.. and therefore not found in the container.
Added the Gaudi boolean property to specify to the algo if it is Data or MC and print or not the WARNING accordingly.
Warning is important for data since the TTs should be always present!
