Explain data flow of self-hosted Sentry's architecture

Problem Statement

From @kanadaj on Discord:

We need a step by step description of what data goes where and last time I checked we kinda lacked that. It's hard to know which container you have to debug if something isn't ingesting, since we have dozens of Kafka queues and processing services, and I know some of the services fees data back from Kafka into Kafka.

And yes, there is a rough outline with a chart somewhere, but it's not really specific enough at this point
