> It will save some time by handling event CLEANUP_CONTAINER asynchronously. 
> This improvement will be useful for cases that cleaning up container cost a 
> little long time(e.g. for our case: we are running Docker container on NM, it 
> will take above 1 seconds to clean up one docker container.  ) and many 
> containers to clean up(e.g. NM need clean up all running containers when NM 
> shutdown).
