Update go-redis client to use Redis 7.x

[fabianaferreira]

What is the purpose of this pull request?

To update our Redis client for cluster mode so that we can use Redis 7.x.

What problem is this solving?

We cannot update the Redis engine version used in our Elasticaches because there was a major release on go-redis to use Redis 7.x. We tried to update it and bumped into this kind of error:

got 4 elements in cluster info address, expected 2 or 3" when used for accessing redis cluster

How should this be manually tested?

Locally, or through a beta version
