Improve TF Agent : boost transformations that are almost completed

We would like to add a functionality to the TFFailover Agent (or eventually elsewhere) to boost the transformations that are almost completed. The use case is when we have several transformations running in parallel and some of them are for instance completed at 99% (99% processed files), we want that they get finished before some others that are less advanced (e.g. 50%). We may want to explore if this can be done by assigning high priorities to the last remaining tasks (jobs) needed to complete a transformation. We should check if the JobPriority parameter can be used for this.
