I'm not so sure but It might fix the second option of issue #215.

I think this time we are ready for the big moment @AkihiroSuda, this will be my first PR for the nerdctl and I'm so excited about this 🥳😋

Sorry, this has to be implemented in pkg/ocihook to support restarting like podman:

$ podman run -d --name foo --restart=always --pidfile /tmp/foo.pid nginx:alpine
$ cat /tmp/foo.pid 
41021
$ kill -9 41021
$ cat /tmp/foo.pid
41100

I did something about OCI hook for supporting pidfile option @AkihiroSuda , but I'm not so sure again :(
