    Description

      1. attemptToGetExecutor and attemptToGetSlotBasedExecutor returns a list of Executors
      2. Establish mongot cursor(s).
      3. After the regular SBE executor is built in attemptToGetSlotBasedExecutor, build another SBE executor for metadata mongot cursor (we don’t need cache it) for sharded scenario.

      Attach the first executor to the pipeline (if not optimized away), and return all executors back in createLegacyExecutor
