> To support fault tolerant, we need to track task states and ensure the correct/allowed
state transitions. 
> Here are the task states:
>         TaskNew,
>         TaskSubmitting,
>         TaskRunning,
>         TaskCompeleted,
>         TaskWaitingForClose,
>         TaskClosedByDriver,
>         TaskFailedByEvaluatorFailure,
>         TaskFailedByGroupCommunication,
>         TaskFailedAppError,
>         TaskFailedSystemError
> Here are the events  taht trigger the state transition:
>         SubmittingTask,
>         RunningTask,
>         CompleteTask,
>         WaitingTaskToClose,
>         CloseTask,
>         FailTaskAppError,
>         FailTaskSystemError,
>         FaileTaskEvaluatorError,
>         FailTaskCommuError
> The state transition diagram is defined the the Fault Tolerant design doc. It is attached.
