Reporting Service for Residential Building

Problem

You've been tasked with creating a reporting service. The reporting service will need to eventually surface many reports, but currently only needs to give a report for the average age of residents in a building.

In order to calculate the report, you will have access to two microservices, one that provides information about buildings and who lives in them, and another endpoint that provides detailed information about those residents.
