Review Comment:
Can we define `topics` in `BrokerStats` and pre-aggregate this topic counts
in `updateStats`?
```
public synchronized void updateStats(
ConcurrentOpenHashMap<String, ConcurrentOpenHashMap<String,
ConcurrentOpenHashMap<String, Topic>>>
topicsMap) {
...
bundles.forEach((bundle, topics) -> {
NamespaceBundleStats currentBundleStats =
bundleStats.computeIfAbsent(bundle,
k -> new NamespaceBundleStats());
currentBundleStats.reset();
currentBundleStats.topics = topics.size();
brokerStats.topics += topics.size(); //pre-aggregate
```
