> is the main implementation of ArtifactStagingService.
> It stages artifacts into a directory; and in practice the passed staging
> session token is such that the directory is different for every job. This
> leads to 2 issues:
> * It doesn't get cleaned up when the job finishes or even when the
> JobService shuts down, so we have disk space leaks if running a lot of jobs
> (e.g. a suite of ValidatesRunner tests)
> * We repeatedly re-stage the same artifacts. Instead, ideally, we should
> identify that some artifacts don't need to be staged - based on knowing their
> md5. The artifact staging protocol has rudimentary support for this but may
> need to be modified.
