      Description

      At present we use oldest_start_ts and oldest_start_txn only in fast truncate operation. We found the issue with this in WT-6494. We need to investigate a solution about repurposing these.
      We need to consider the impact of this repurpose for upgrade and downgrade. The scope of this ticket is:
      1. To make code changes and have a PR.
      2. Run a MongoDB patch build and WT stress testing build to understand the fallout.
      3. Analysis of the impact for upgrade and downgrade.
