SneakerNet Required Changes

[JBorrow]

Includes all the changes required for SneakerNet functionality.

Need to think about the callback system. I think we can have downstream callback to site and create remote instance at that time (to avoid 'fake' remote instances that do not yet exist). But need to think about ordering in sync tasks, as they assume 'does not have remote instance' means 'still needs to be transferred'. That's not compatible with our async methodolgy.

Need to figure out why the librarian instances aren't ingesting their new 'name field.

To be done:

• CLI integration
• Admin endpoints for creating librarians. - Remote librarian endpoints #59
• Turn off API docs setting - Turn off API docs #60
• Documentation!
• Maximal runtime for background jobs.
