Describe the bug

VictoriaMetrics may return corrupted data to the user since VictoriaMetrics does not persist any checksum/CRC information, and VictoriaMetrics does not use the checksum feature of the zstd compression method.

To Reproduce

Data corruption may happen in memory, and silent data corruption on a disk is not that rare.

Expected behavior

IMHO, data integrity is very important, corrupted data is worse than no data.

Maybe we can use some attached storage services with the checksum feature, such as Kubernetes PVC, but I think this function is fundamental to VictoriaMetrics and we should implement it inside VictoriaMetrics.
