TrigCost: Extend ROS Monitoring

Aleksandra Poreba requested to merge aporeba/athena:cost-new-rob-hist into 22.0

Add new histograms requested in ATR-26131 (examples are available there):

  • Monitor ROS
    • How many times ROB was requested for the ROS request
  • Monitor Chain
    • How many ROBs were requested for ROS request
    • How many times data was requested for ROS per event
    • How many ROBs were requested for ROS per event

To simplify sharing the data related to ROS requests (for example ROS-ROB mapping, ROS to bin mapping) a class was added, mimicking CostData. It is created once, in the initialization of the TrigCostAnalysis algorithm, and then, via CostData passed to monitors - this way the mappings won't be recalculated many times per event.

Some of the histograms are actually TProfile type - handling it was also added to the classes of the Cost Analysis.
