[nbbeeken]

Description

Motivation and Context

• Bugfix
• New feature - parity with legacy DE
• Dependency update
• Misc

Open Questions

For reviewers:

• Did I make good use of hooks by writing useIndexProgress?
• The getInProgressIndexInfo used to just list stub indexes because even in progress ones would be listed as "ready" while they continued to build on the server. We now will list "real" indexes via this function. Is that the right approach?

Dependents

Types of changes

• Backport Needed
• Patch (non-breaking change which fixes an issue)
• Minor (non-breaking change which adds functionality)
• Major (fix or feature that would cause existing functionality to change)
