This extends Request.Redis with a bunch of function wrappers that (mostly) make a single Redis call. The function names describe what the functions do in Swiftarr API terms, keeping the Redis keys and specific commands used internal to this file. When looking at the Redis database you can refer to this file to see what various keys are used for, and having all the Redis code here makes it much easier to reason about changes to how we structure data in Redis.

Unlike Postgres with Fluent, Redis doesn’t provide us with a centralized data model for how the db is structured. Having code all over the app call hset directly makes it difficult to answer questions like, “What fields should exist in this hash set?” So, all that is centralized here.
