Module doesn't properly handle 429 responses from Akamai

I created an MR with code to put 429 responses into a PROCESSING state, which should leave them queued for Purge to handle later.

However, I admit I'm having a hard time testing this. Creating a situation where I'm reaching the my client's Akamai rate limit would be both unpredictable, and bad for site performance. I can look into writing a test to generate a 429 response, but I also admit that's above my current PHPUnit abilities.
