Review comment:
Changed the autoCompactionSnapshotPerDataSource into a
AtomicReference<Map<String, AutoCompactionSnapshot>>.
We will build a new autoCompactionSnapshotPerDataSource of snapshots in each
compaction run then replace (atomically) the whole map
(autoCompactionSnapshotPerDataSource) at the end in `makeStats`
