Issue description

Step 7.3 of GE "Developing REST based Microservices" states an environment variable is required because application.properties already contains the following:

quarkus.rest-client."com.redhat.training.client.ExpenseServiceClient".url=http://localhost:8080

In reality, the content is slightly different, because configKey parameter is used:

quarkus.rest-client.expense-service.url=http://localhost:8080
