QEMU has a monitor command 'set_cpu' which allows a specific CPU to be toggled between online& offline state. libvirt CPU hotplug does not work in terms of individual indexes CPUs. Thus to support this, we iteratively toggle the online state when the total number of vCPUs is adjusted via libvirt NB, currently untested since QEMU segvs when running this! * src/qemu/qemu_driver.c: Toggle online state for CPUs when doing hotplug * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h, src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Add monitor API for toggling a CPU's online status via 'set_cpu
