[HusterWan]

Signed-off-by: Michael Wan zirenwan@gmail.com

Ⅰ. Describe what this PR did

Killing a container after pouchd service quit, then start the pouchd service, the killed container's status still be running

so we must sync all abnormal containers's status when starting the pouchd service.

1. pouch ps choose a container to perform an experiment, in this case, we choose 80ec87

root@osboxes:pouch (master) -> pouch ps
Name     ID       Status       Created       Image                                            Runtime
c19218   c19218   Up 2 hours   2 hours ago   registry.hub.docker.com/library/busybox:latest   runc
adb4df   adb4df   Up 2 hours   2 hours ago   registry.hub.docker.com/library/busybox:latest   runc
80ec87   80ec87   Up 2 hours   2 hours ago   registry.hub.docker.com/library/busybox:latest   runc
6dd2b3   6dd2b3   Up 2 hours   2 hours ago   registry.hub.docker.com/library/busybox:latest   runc
6f3fd2   6f3fd2   Up 3 hours   3 hours ago   registry.hub.docker.com/library/busybox:latest   runc

2. kill the container process after pouchd service quit.

root@osboxes:pouch (master) -> ps aux | grep 80ec87
root     14196  0.0  0.0 112660   976 pts/3    S+   04:19   0:00 grep --color=auto 80ec87
root     31751  0.0  0.1   8924  2860 pts/5    Sl   01:22   0:00 containerd-shim -namespace default -workdir /var/lib/pouch/containerd/root/io.containerd.runtime.v1.linux/default/80ec87c8336f4856507cdcdbbabb7e4d0dd83fc2b7325d1de7da05447a42435a -address /var/run/containerd.sock -containerd-binary /usr/local/bin/containerd -runtime-root /run
root@osboxes:pouch (master *) -> kill 31751

3. start pouchd service again, then the container'status should be stopped:

root@osboxes:pouch (master *) -> pouch ps -a
Name     ID       Status       Created       Image                                            Runtime
c19218   c19218   stopped      3 hours ago   registry.hub.docker.com/library/busybox:latest   runc
adb4df   adb4df   stopped      3 hours ago   registry.hub.docker.com/library/busybox:latest   runc
80ec87   80ec87   stopped      3 hours ago   registry.hub.docker.com/library/busybox:latest   runc
6dd2b3   6dd2b3   Up 3 hours   3 hours ago   registry.hub.docker.com/library/busybox:latest   runc
6f3fd2   6f3fd2   Up 4 hours   4 hours ago   registry.hub.docker.com/library/busybox:latest   runc
