Here's the offending line:

https://github.com/kyknow/nestjs-redis/blob/master/lib/redis-client.provider.ts#L17

If you pass in a url, any other options are ignored:

RedisModule.register({
      url: process.env.REDIS_URL,
      keyPrefix: process.env.REDIS_KEY_PREFIX,
    }),

What's the intended behavior here? If the URL overwrites all other options, we should document and enforce with types.

Thanks!
