Add Provider to Support Apple's Developer System Status Page

[mw-mmiller]

Summary

As part of our mobile development build process, we pull information and files from Apple's developer portal (specifically, "Certificates, Identifiers & Profiles"). Knowing the operational status of the portal would be greatly beneficial for us.

https://developer.apple.com/system-status/

Desired Behaviour

Ideally, the solution would work very similarly to existing providers. I understand that Apple doesn't give a history of the system's status so simply a reflection of the current status of its services would be sufficient.
