L1 TRT monitoring implemented - ATR-28372
The main goal of this merge request is to add a monitoring algorithm for the L1 TRT trigger.
In TrigMinBiasMonitoring a new c++ algorithm is implemented for the TRT monitoring together with the python interface and configuration. In PhysicsP1_HI_run3_v1.py the monitored 'HLT_noalg_L1TRT_FILLED' trigger chain is added to the monGroup.
