QEMU is gaining a new monitor command netdev_add for hotplugging NICs using the netdev backend code. We already support this on the command this, though it is disabled. This adds support for hotplug too, also to remain disabled until 0.13 QEMU is released * src/qemu/qemu_driver.c: Support netdev hotplug for NICs * 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 support for netdev_add and netdev_remove commands
