Re: [PATCH v8 09/18] qemu: Implement qemu driver for throttle API

From: Chun Feng Wu <danielwuwy(a)163.com&gt; ThrottleGroup lifecycle implementation, note, in QOM, throttlegroup name is prefixed with "throttle-" to clearly separate throttle group objects into their own namespace. * "qemuDomainSetThrottleGroup", this method is to add("object-add") or update("qom-set") throttlegroup in QOM and update corresponding objects in DOM * "qemuDomainGetThrottleGroup", this method queries throttlegroup info by groupname * "qemuDomainDelThrottleGroup", this method checks if group is referenced by any throttle in disks and delete it if it's not used anymore * Check flag "QEMU_CAPS_OBJECT_JSON" during qemuDomainSetThrottleGroup when vm is active, throttle group feature requries such flag * "objectAddNoWrap"("props") check is done by reusing qemuMonitorAddObject in qemuDomainSetThrottleGroup Signed-off-by: Chun Feng Wu <danielwuwy(a)163.com&gt; * Apply suggested coding style changes. * cleanup qemu Get ThrottleGroup. * Update the version to 11.1.0.
