Save a worker task report (time, memory etc.)
Somewhat related to https://gitlab.cern.ch/cp3-cms/bamboo/-/issues/87 . @fbury created a very useful script to get the define and fill time (for each worker task, and averaged per sample) from the log file. It would be straigthforward to write those numbers to a file from the worker task, and read them from there (this may also be useful to optimise the splitting by hand, or with a pilot job).
