Good to include config server, build service, service registry gateway and API portal in the architecture picture

In unit 1, we are using Config server, build service, service registry, gateway and API portal for the sample app, which is great. I think we may need to mark this inside architecture picture. Otherwise customer may not be able to understand why they trigger various commands for these components.

We have a ton of details however we simply have limited real estate .. hence, we are omitting config and service registry details
