   It is not easy to write a UT for the log4j2 appender so I just test it manually.
   
   Change the 'appender.console.maxSize' property in log4j2.properties to a very small value, for example, 1K, you will soon see this output when running UT in IDE
   
   ```
   2022-04-12 22:44:20,366 Time-limited test ERROR Log size exceeded the limit 1024, will stop logging to prevent eating too much disk space
   ```
   
   So I think this approach works.
   
   And I set default value to 1G, which should be enough for most cases...
   
   @busbey @ndimiduk FYI. I think this could solve the recent space problem of our ci system.
