Windows doesn't allow to remove dir with opened files. Usually it's a case for snapshots, hard cannot be removed if file is openned. With this change, dir will be renamed and properly deleted at the next process start. It's recommended to restart vmstorage/vmsingle for snapshots deletion completion periodically. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/70
