Subject: [PATCH] Restart rootless docker after host updates

Upgrading containerd does not restart the agent's rootless dockerd, and
no reboot is triggered, so the daemon keeps using the old containerd
shims. Containers then fail to start until the host reboots, which
broke scenario setup in benchmark runs.
