IoTDB can not start due to IoTDBConfigCheck

Some configurations in iotdb-engine.properties is unmodifiable after the first start, such as which precision a long timestamp represents.

If you change some config, we will check this, stop the server and remind you.

If you insist on changing these config(and ensure this will not cause bug), you could modify the data/system/schema/system.properties and restart.

首先检查 iotdb-engine.properties 的配置处理以及持久化数据/system/schema/system.properties 路径。在更改 timestamp precision 等配置后复现启动失败，然后确定该更改的预期行为，并验证重启处理是否与其一致。
