codis: file /tmp/codis/data/codis3/codis-demo/topom already exists

[yaoyinnan]

When deploying codis, the tmp file was not cleaned up due to abnormal exit, and it needs to be cleaned up manually. The path of the conflicting file is not indicated in the log. Since this file is used to mark a codis cluster, it cannot be directly overridden in code when duplicates are detected.
