Sub-task 2: Add support for the “HitRate” Collector mode 

Additional task 

Add three messages to the output, regardless of success or failure of the task as a whole, that show the following:

  1. The number of failures in the measurement with the largest number of failed actions

  2. The lowest and highest “hit percentage”

  3. The average and median “hit percentages”. If there is no strict median value, use the average of the two center-most values.
