Migrate ILLiad OCR Process to use hosted Illiad

[tpendragon]

Summary

The library will be switching to hosted Illiad in August. @kevinreiss says we will need to do two things:

1. Change the folder that Figgy's FileWatcher looks at for new ingests - it'll be in a different place.
2. Upload the resulting OCR'd PDFs via sftp to hosted Illiad, instead of moving it to a folder.

Impact

We're switching to hosted ILLiad in August. We'd need to do this work in July.

Priority recommendation

• asap
• within the next 3 weeks
• PO will prioritize

Blockers

• What is the folder we should pull files from?
• What's the SFTP information?
