    Description

      1. Remove this if-statement/call into onCompletion.
      2. Place a call to ReshardingMetrics::onStepDown() here contingent on the stepdownToken being cancelled.
      3. Remove the current call to onStart in the class and instead place it here, past the gate checking if we're coming from stepup.
      4. Place a call to onStepUp past this line.
