Raphaël 984d2ac767 fix: write index.yaml file atomically (#7954) ... * fix: write index.yaml file atomically This refactors the already-existing `AtomicWriteFile` utility to a central location and uses it to write index files atomically. This is done to avoid having half-written index files break client requests. Drive-bys: - Add test for AtomicWriteFile. - Add test IndexFile.WriteFile.
