If containerd-shim-runc-v1 process dead abnormally, such as received kill -s 9 signal, panic or other unkown reasons, the containerd-shim-runc-v1 server can not reap runc container and forward init process exit event. This will lead the container leaked in dockerd. When shim dead, containerd will clean dead shim, here read init process pid and forward exit event with pid at the same time.
