What would you like to be cleaned:

Make sure workload controller calling QueueSecondPassIfNeeded would remove the workload from second pass queue if no longer needed there.

The scenario:

1. node failure controller adds the unhealthyNodes to the workload
2. workload controller adds the workload to QueueSecondPassIfNeeded
3. node failure controller removes the node from unhealtyNodes becuase the node is now healthy
   Issue: workload controller does not remove the workload from QueueSecondPassIfNeeded

Why is this needed:

To avoid potential race condition bugs, and make the interaction between controllers easier.
