come up mechanism to download (large) input files

[boegel]

Should use JSON or YAML file as input, which specifies:

• filename
• URL
• SHA256 checksum

If the files are not available yet in a "cache" directory, it should try and download it, and it should always verify the checksum

Would it be useful to store them in a CVMFS repo?

EESSI/software-layer#170 may also be relevant, it tried to add similar functionality for the pilot repo.

Yes, but let's cross that bridge when we get there.

We currently don't have an app in view for the test suite that requires huge input files, at least not in the short term.
