LAr online monitoring fixes based on M11

These are changes needed at P1 to run LAr monitoring during M11. In addition CA based configs are added, we plan to switch to them during/after M12.

Pinging @lily to check if DT changes are correct.

Sorry for the LArCalorimeter/LArMonitoring/python/LArRawChannelMonAlg.py change, I had to remove W$ EOL, the content itself is not changed.
