> When a queue's flow control state changes, the broker should issue an QMF event to notify management clients.
> A rough sketch of a possible schema implementation for the event:
>   <eventArguments>
>     ....
>     <arg name="qName"     type="sstr"   desc="Name of a queue"/>
>     <arg name="msgDepth"  type="count32" desc="Current size of queue in messages"/>
>     <arg name="byteDepth" type="count32" desc="Current size of queue in bytes"/>
>     <arg name="active"   type="bool" desc="True if flow stopped, else flow allowed"/>
>   </eventArguments>
>   <event name="queueFlowControl"   sev="inform" args="qName, active, msgDepth, byteDepth"/>
