This change contains QMP requests for ThrottleGroup
* ThrottleGroup is updated through "qemuMonitorJSONUpdateThrottleGroup"
* ThrottleGroup is retrieved through "qemuMonitorJSONGetThrottleGroup"
* ThrottleGroup is deleted by reusing "qemuMonitorDelObject"
* ThrottleGroup is added by reusing "qemuMonitorAddObject"
* "qemuMonitorMakeThrottleGroupLimits" will be used by building qemu cmd as
well
Signed-off-by: Chun Feng Wu <danielwuwy(a)163.com>
* change throttle group config conversions P to U allow zero.
* Apply suggested coding style changes.
