externalPulsar.enabled property isn't honored

[david-streamlio]

When I install Milvus from the latest Helm chart using the following command, I see that pulsar and all of the associated pods are created.

Steps to reproduce:

1. helm repo add milvus https://zilliztech.github.io/milvus-helm/
2. helm repo update
3. helm install milvus-test --set externalPulsar.enabled=true milvus/milvus
4. kubectl get pods | grep pulsar

@david-streamlio You need manually disable default pulsar pods like this:

helm install milvus-test --set externalPulsar.enabled=true --set pulsarv3.enabled=false milvus/milvus

@LoveEachDay Maybe we should add condition check to auto disable pulsarv3 when externalPulsar.enable is set?
