> This ticket introduces an atomic commit transaction for file store.
> # Before calling {{{}FileStoreCommitImpl#commit{}}}, user should first call
> {{FileStoreCommitImpl#filterCommitted}} to make sure this commit is not done
> before.
> # Before committing, it will first check for conflicts by checking if all
> files to be removed currently exists.
> # After that it use the external {{FileStoreCommitImpl#lock}} (if provided)
> or the atomic rename of the file system to ensure atomicity.
> # If commit fails due to conflicts or exception it tries its best to clean
> up and aborts.
> # If atomic rename fails it tries again after reading the latest snapshot
> from step 2.
