 1. MODE:  This can be configured as grpc or http or grpc-and-http to allow for easy migrations.
-2. CACHE: local uses in process memory to cache backup values, while redis, will use redis. Redis
-          will store the config in a single key entry that ends up being "statsig::{sha256(sdk_key)}".
-          This allows you read the value back from the SDK data adapter if needed.
