-----------------------------------------

It looks more discussion is required, cancelling the patch. Let keep it open for discussion.

> 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).
