Julia tools running scenarios in parallel need to compile the same code multiple times

When we automatically parallelize execution of scenarios, each tool instance needs to run in a separate process or kernel, otherwise they can't run in parallel.

That's ok, but the problem is julia tools need to compile the code the first time it's run. So if we spawn multiple julia sessions to run the same code, they will all be running the same compilation statements. There must be a way to compile only once into a system image, and then use that system image in all other processes to save time.
