Add a new batsim output file that contains the simulation begins data
Some of the information that is available in the simulation begin message are not exported by batsim but are needed for post analysis (e.g, workload hash/filename mapping, configuration, resource list and properties, etc.)
I propose that Batsim dumps the content of this message directly in a json file, so it can be used afterward without parsing simulation logs (this is what I'm doing right now...).
I propose <prefix>_metadata.json
, so we can extend this with any kind of information in the future.
