KUDU-3180: prioritize larger mem-stores in time-based flusing
Current time-based flush policy will always pick a mem-store
that haven't been flushed in a long time instead of a mem-store
anchoring more memory, this may lead to:
- more memory used by mem-stores.
- more small rowsets on disk so we need to do more compaction.
This patch improve current flush policy by considering both
mem-stores' size and time since last flush. When a mem-store
become large or old enough, it will be more likely to flush,
then we can avoid anchoring large (but below the threshold)
mem-stores or WALs for too long.
