Do I have to enable proxy to access the broker from outside the Pulsar cluster?

**Describe the bug**
I would like to access Pulsar brokers from outside the Kubernetes cluster without using pulsar-proxy.

**Version**
```
4.0.3
```

**To Reproduce**
Steps to reproduce the behavior:
1. Deploy a Pulsar cluster (without proxy) using the Pulsar Operator
2. Modify broker config to include advertisedListeners for external access
```
[root@master ~]# for i in `seq 0 2`; do kubectl -n pulsar-operator-system exec -it pulsarcluster-sample-broker-$i -- cat /pulsar/conf/broker.conf |egrep 'advertisedListeners|advertisedAddress|internalListenerName'|grep -v "#";doneDefaulted container "broker" out of: broker, wait-bookkeeper-ready (init)
advertisedAddress=pulsarcluster-sample-broker-0.pulsarcluster-sample-broker.pulsar-operator-system.svc.cluster.local
advertisedListeners=internal:pulsar://10.0.0.100:6650,external:pulsar://192.66.111.120:30650
internalListenerName=internal
Defaulted container "broker" out of: broker, wait-bookkeeper-ready (init)
advertisedAddress=pulsarcluster-sample-broker-1.pulsarcluster-sample-broker.pulsar-operator-system.svc.cluster.local
advertisedListeners=internal:pulsar://10.0.1.132:6650,external:pulsar://192.66.111.148:30650
internalListenerName=internal
Defaulted container "broker" out of: broker, wait-bookkeeper-ready (init)
advertisedAddress=pulsarcluster-sample-broker-2.pulsarcluster-sample-broker.pulsar-operator-system.svc.cluster.local
advertisedListeners=internal:pulsar://10.0.2.209:6650,external:pulsar://192.66.111.166:30650
internalListenerName=internal
[root@master ~]#
```
3. Run a Pulsar Go client on a host outside the cluster with:
```
pulsar.NewClient(pulsar.ClientOptions{
URL: "pulsar://:30650",
ListenerName: "external",
})
```
4. Observe producer behavior
```

exit status 1
```

**Expected behavior**
We expect that by exposing broker pulsar:// port via NodePort and configuring advertisedListeners, Pulsar clients can work without proxy.
