Adding a new machine checklist

- Add support for batch system query status etc. in the Perl script
- Create nightly Jenkins task that doesn't conflict with existing upload schedule (spaced out from others)
- There may be issues with concurrent uploads?

Start by locating the Perl script and reviewing the existing Jenkins upload schedule. Confirm the required batch-system status queries and investigate whether concurrent uploads are safe. Done means the nightly task is added without conflicting with existing uploads and the checklist items are addressed.
