    Applied WorkOrderSelectionPolicy.

    This PR introduced `WorkOrderSelectionPolicy` to choose the next 
`WorkOrder` for the execution, and uses the following policy: first `FIFO` for 
`RebuildWorkOrder`s, and then `LIFO` for normal `WorkOrder`s.
    This policy favors any `RebuildWorkOrder` to reduce the total operator 
completion time, and normal `WorkOrder`s generated from data pipeline messages. 
Finally, a normal `WorkOrder` from a larger `OperatorIndex` is preferred.
    Assigned to @jianqiao.
