[FLINK-3948] Protect RocksDB cleanup by cleanup lock
Before, it could happen that an asynchronous checkpoint was going on
when trying to do cleanup. Now we protect cleanup and asynchronous
checkpointing by a lock.
This was what caused `EventTimeWindowCheckpointingITCase` to fail. I now
ran it more than a 100 times on travis and haven't observed a build failure
related to this.
