* 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.
