Review comment:
- ```AUTO_FLUSH_BACKGROUND``` don't support strong consistence.
- ```MANUAL_FLUSH``` support strong consistence by wait for one flush() and
join() before triggering another flush. but in this mode, flush data only
depend on checkpoint trigger. is it suitable in flink sink? should we add
another strategy(count、size) ? we shoud do more in another PR.
