Feature: Surface in the UI users that did not backfill via the ETL or that are currently being backfilled via the ETL

As a user, I want to be notified in flows of the application that involve contributors/users if they were backfilled unsuccessfully as well as if they are in the process of being backfilled.

Relates to https://github.com/open-sauced/etl/issues/171

Scenarios:

• Tracking contributors in workspaces
• others?
