Review Comment:
How is this logic? This is simply walking pointer references to get a size
off a collection.
```
managedBroker.getQueueRegion().getDestinationMap().size()
```
The connection counters do similar

> Right now, to monitor the number of destination, the only way is to read the
> destinations MBean and get the total destination. However, this means reading
> all destination names into memory, if the user has 10K+ destination with long
> destination name, it will be a large amount of memory just to monitor the
> number of them.
> The proposal here is to add either a new MBean value or a method to obtain
> that data. We can also add a method to retrieve the first K destination as
> well.
