Review Comment:
Looking at the code here, `createMetadataWithoutBase` would be invoked if
metadata file doesn't exist for the latest snapshot. This means whatever latest
Iceberg metadata file available would be referenced by the Iceberg readers.
Creating the new one and deleting old one quickly can cause some race
conditions. Also, it would make it less consistent specially if someone
disables deletion of metadata file altogether with option
`delete-after-commit.enabled`.
