…finished building/installing Before this commit `RaftMetrics.snapshot` contains the last log id of a snapshot that is **going** to install. Therefore there is chance the metrics is updated but the store does not. In this commit, `RaftMetrics.snapshot` will only be updated when a snapshot is finished building or installing, by adding a new field `snpashot` to `IOState` for tracking persisted snapshot meta data. - Fix: databendlabs#912
