Review Comment:
thanks @KKcorps The reason to have a separate file is that We should mark
snapshot persisted by TTL differently from the regular snapshot, so
validDocsIdsSnapshot from upsertTTL will not be override by SnapshotEnabled
feature. We can also use snapshot for segment compaction and other upsert
improvements.
Another potential solution is disable `enableSnapshot` for upsert TTL so
that both snapshots won't overwrite each other.
