Review Comment:
From a personal point of view, I think we should not clean up during the
heartbeat. If the leveldb is not cleaned up successfully or an exception is
thrown, is the heartbeat successful or failed?
The heartbeat is mainly to report container information and trigger
scheduling, it is best not to clean up.
