The redis_proxy filter that envoy has implemented does not support read requests routing in redis M/S clusters mode！

*Title*: *The redis_proxy filter that envoy has implemented does not support read requests routing in redis M/S clusters mode！*

*Description*:
>The redis M/S cluster mode is relatively frequently used in prod env。but，[Control read requests routing. This only works with Redis Cluster](https://www.envoyproxy.io/docs/envoy/v1.21.2/intro/arch_overview/other_protocols/redis.html?highlight=redis). Therefore, will it consider adding support for [read requests routing](https://www.envoyproxy.io/docs/envoy/v1.21.2/api-v3/extensions/filters/network/redis_proxy/v3/redis_proxy.proto#envoy-v3-api-field-extensions-filters-network-redis-proxy-v3-redisproxy-connpoolsettings-read-policy) in M/S cluster mode in future new versions of envoy?
