Universal redis client

[ederuiter]

Currently chirpstack has it own thin wrapper around deadpool-redis (https://github.com/chirpstack/chirpstack/blob/master/chirpstack/src/storage/mod.rs)

In the go-redis client there is a universal client that allows you setup either a normal/cluster/sentinel client depending on the config you give. See https://redis.uptrace.dev/guide/universal.html

Would you be open to accepting a PR for a universal redis client in deadpool-redis?
This would prevent code duplication in users of deadpool-redis and would allow them to easily switch between normal/cluster/sentinel clients

Sure thing. I always wondered why there needed to be three distinct pools for that. I only use a single redis instance so I've never actually bothered with redis cluster/sentinel. It is purely driven by PRs from the community.
