    Description

      Upon rollback, there are several scenarios that can occur, given these time periods for the start and end of rollback:
      1. Prior to index build starting.
      2. During index build phase 1 (collection scan and inserting into sorter(s))
      3. During index build phase 2 (bulk load of index table(s))
      4. During index build phase 3 (catch up from side table(s))
      5. After index build completes.

      This work should only begin after we have a stable basic rollback procedure that handles resumable index builds. See SERVER-48418.
