task status bug

   New modification plan:
   1.The method runProcess() of the MasterExecThread class. Update instance 
status before submitting task.
   
   ```
               updateProcessInstanceState();
   
               if (canSubmitTaskToQueue()) {
                   submitStandByTask();
               }
   
               if (processInstance.IsProcessInstanceStop()) {
                   break;
               }
   
               try {
                   Thread.sleep(Constants.SLEEP_TIME_MILLIS);
               } catch (InterruptedException e) {
                   logger.error(e.getMessage(),e);
               }
   ```
   
   2.The method getSubmitTaskState() of the ProcessDao class. If instance 
status is failure, the task status is set to kill.
   
   ```
           if( processInstanceState == ExecutionStatus.READY_PAUSE){
               state = ExecutionStatus.PAUSE;
           }else if(processInstanceState == ExecutionStatus.READY_STOP
                   || processInstanceState == ExecutionStatus.FAILURE) {
               state = ExecutionStatus.KILL;
           }else{
               state = ExecutionStatus.SUBMITTED_SUCCESS;
           }
   ```
