-------------------------

             Summary: [ confignode/datanode configuration parameters ] Removes 
the space character from both the start and the end of the parameter value
                 Key: IOTDB-4673
                 URL: https://issues.apache.org/jira/browse/IOTDB-4673
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: mpp-cluster
            Reporter: 刘珍
            Assignee: Jialin Qiao


举个例子
data_region_ratis_max_retry_attempts = 2 
confignode配置文件中的这个参数值后面不小心多了1个空格"2 " ，启动confignode报错
confignode/datanode配置参数在代码里需要过滤掉空格。
