(broker) Copy all files from utils and .py files in repo root to final evaluator

This will lead to some double copying (for eg, evaluator.py)

This shouldn't matter now since evaluator.py is simply getting copied over. If the template is changed in the future and some pre/post lines are added to the file, this might break.
