[A-MQ, RuntimeConfigurationBroker] allowing policy that applies to multiple destination to be updated.

Trying to update a destination policy at runtime (using the RuntimeConfigurationBroker) that applies to multiple destinations is restricted. The following destination policy update (it is used by multiple destination)~~~~
<policyEntry memoryLimit="1gb" optimizedDispatch="true" producerFlowControl="false" queue=">" />
~~_{prints out the following}~~
[ActiveMQ Broker[XXXX]Scheduler] INFO RuntimeConfigurationBroker - cannot modify policy matching multiple destinations:[org.apache.activemq.broker.region.policy.PolicyEntry@XXX, org.apache.activemq.broker.region.policy.PolicyEntry@XXXX], destination:queue://>
~~~~It would be good to remove this restriction to make it more usable.
