add a test case to demonstrate the exceeded memory usage percent. When the memory usage limit of queues is larger than the global/broker memory usage limit and PFC is disable, the exceeded memory usage percent is present.I believe this is a unsuitable configuration while the broker keeps dumb.
The message cursor of queues only checks its own memory usage to see if it has space regardless of its parent(that's the broker) and if the queue memory usage limit is far larger than the broker's,the cursor can keep putting messages into to cache/memory for a long time, that's why the exceeded memory usage percent happens.I believe this can lead to OOM eventually if the memory usage limit for queues is X GB.
