Copy to Vast: status indicator

[pgarrison]

User story

Scientists 1 and 2 are working on a project that needs to use file A on local storage, but File A is only on the cloud. Scientist 1 uses BFF to copy the file to the Vast. The file is 4TB so it isn't immediately available. Scientist 2 goes to BFF to do the same thing: they would like to know if the download is already in progress.

Design

In “canonical file path field” write “Copying to Vast in progress…” (italics) for in-progress downloads

Implementation details

• Cloud only: shouldBeInLocal is False
• Download in progress: shouldBeInLocal is True and eviction date is null
• Download complete: shouldBeInLocal is True and eviction date is non-null

More design decisions needed: The plan above uses "File Path (Canonical)" but does not account for "File Path (Local)", since our test usage of BFF didn't surface files with a "File Path (Local)". Need to get clarity on how the three paths (Cloud, Local, Canonical) interact and decide which to display for downloads in progress. "Canonical" path may be of little value to users, compared to the other two.

We can also use the presence of a local path to identify whether the download is in progress
