> 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).
