Description

Currently, the tagIndex in metadata module uses mlog to recover.

However, if user alters one timeseries' tag, the tag will only be updated to the tagLogFile rather than mlog.

Thus, after tag update operation, the recover won't use the up-to-date tag information in tagLogFile but use the outdated tag information in mlog.
