Hercules Retail 360 iOS App - New services and general cleanup

The Retail 360 iOS App is a tool used by Hercules employees in their retail stores.  The app allows for looking up customer details and will eventually contain lots of functionality for managing customer accounts, making changes to their accounts, and adding notes, sending emails, etc...
We have released version 1 of the app to some employees, and version 2 is nearing completion.  As we add more and more functionality, we need to ensure that the existing functionality isn't broken by any new changes.

This challenge will add a couple new services - one for showing outages for a customer, and one for saving device receipts to a CMS instead of S3.  This challenge will also clean up a few things and ensure we maintain consistency with the web version of the app.
