Allow for targeting one Redis store while using indexes as key prefixes #32
Description
To account for scenarios where a redis cache is already being used for other parts of a bot letting people target a single redis store while prefixing keys with indexes as an alternative approach may be helpful.
I'm thinking that with the recent addition of fb2219d redis.ResourceClient could have a toggle on it which switches it between two different key strategies where one formats all the keys as something along the lines of "{index}:{actual_id}" (where overrides don't effect the used index) while the other is just the actual id and a short hand method which sets overrides for all the known indexes so that switching over to a prefix cache implementation would look something like
cli = RedisClient(...).key_prefixing(True).override_all_indexes(int)
