More robust handling of metadata command in compute worker
The metadata
file of a scoring or ingestion program is supposed to contain something like this:
command: python3 scoring.py $argument [...]
However, organizers may provide empty file, or file simply containing a string. In such case, we simply want the command to be set to None
instead of having the compute worker crashing.
