[PATCH v2 0/6] ch: handle events from cloud-hypervisor

changes from v1->v2: * Rebase on latest master * Use /* */ for comments * Remove fifo file if already exists * Address other comments from Praveen Paladugu cloud-hypervisor raises various events, including VM lifecylce operations such as boot, shutdown, pause, resume, etc. Libvirt will now read these events and take the necessary actions, such as correctly updating the domain state. A FIFO file is passed to `--event-monitor` option of cloud-hypervisor. Libvirt creates a new thread that acts as the reader of the fifo file and continuously monitors for new events. Currently, shutdown events are handled by updating the domain state appropriately.
