Add support for redis clusters

Can we add support for connecting to redis clusters? When using Amazon ElastiCache Serverless they require you to connect via the cluster method. From what I have seen the redis client should support this - take a look at this page:

https://github.com/redis/ioredis?tab=readme-ov-file

Main thing is we need to support connecting to a Redis.Cluster object.

const Redis = require("ioredis");

const cluster = new Redis.Cluster([
  {
    port: 6380,
    host: "127.0.0.1",
  },
  {
    port: 6381,
    host: "127.0.0.1",
  },
]);
