      Description

      This jira does the following:
      1. When do rollback for rolling upgrade, we should call FSEditLog#initJournalsForWrite when initializing editLog (just like Upgrade in HA setup).
      2. After the rollback, we also need to rename the md5 file and change its reference file name.
      3. Add a new unit test to cover rollback with HA+QJM
