[libvirt] [PATCH] qemu: lifecycle: make agent-mode shutdown and reboot timeout



When we shutdown/reboot a guest using agent-mode, if the guest itself blocks infinitely,
libvirt would block in qemuAgentShutdown() forever.
Thus, we set a timeout for shutdown/reboot, from our experience, 60 seconds would be fine.
