Add messaging scenarios

[sonwan2020]

Message is a key concept to microservices
It is better to add messaging components to the petclinic solution and demo

Yes, add as optional to the end of the lab and based on what's already there in https://azure-samples.github.io/java-microservices-aks-lab/docs/05_lab_messaging/05_openlab_messaging_aks.html

And I guess we want to go for both messaging (service bus) and eventing (event hub), right?

My initial plan is, give messaging or event, they have same topology on the structure.

It depends on the requirement and the efforts
