This is mostly to workaround an issue with gRPC based shims after containerd restart. If a shim dies while containerd is also down/restarting, on reboot grpc.DialContext with our current set of DialOptions will make us wait for 100 seconds per shim even if the socket no longer exists or has no listener.
