Summary: Add a flag in `IOOptions` to request the file system to make best efforts to detect data corruption and reconstruct the data if possible. This will be used by RocksDB to retry a read if the previous read returns corrupt data (checksum mismatch). Add a new op to `FSSupportedOps` that, if supported, will trigger this behavior in RocksDB.
