Redis cluster - read-replica routing

[jstorqhonor]

I've written some logic to do basic read-replica routing for a redis cluster but that extends the flask_caching.Cache() object to get benefits of the @cached annotation. I cannot find sufficient evidence that the actual RedisClusterCache client is actually meant for simple cache gets and sets with just routing logic without the slot, shard and pubsub logic that is really unnecessary and feels more about managing a redis cluster. Would there be any interest?
