Otherwise, we are risking to leak DNS entries which happens when ContainerName is passed to `weave reset` and subsequent internal call to nameserver creates a new entry instead of replacing the old one. The ContainerID of the new entry is set to ContainerName and in such case stopping the container will not remove the new entry.
