Add documentation for using Cloud Memorystore with TLS and/or authentication about spring-cloud-gcp

[meltsufin]

Thanks for posting the documentation issue! Anything that is specific to Redis use through Cloud Memorystore would be good to document. This includes host and port, and perhaps auth. However, we do not have any Redis-specific code in the repo. So, I think it's best to rely mostly on official Spring Boot documentation on Redis. I guess this link: https://docs.spring.io/spring-session/reference/guides/boot-redis.html#boot-redis-configuration

We'd be happy to accept a contribution for this issue. Thanks!

There might be no Memorystore/Redis-specific code in your repo, but there are some Cloud Memorystore-specific configuration instructions that would be helpful to have in the Spring Cloud GCP Memorystore docs, because the generic Spring Boot docs won’t cover configuring Cloud Memorystore specifically.

The Spring Boot Redis docs will explain all configuration options, but it took me a while to figure out how to connect to Cloud Memorystore specifically. I figured the Spring Cloud GCP Memorystore docs would be a good home for this guidance.

That is a section in the Spring Session docs. This is the section in the Spring Boot 3.2.x docs: https://docs.spring.io/spring-boot/docs/3.2.x/reference/html/data.html#data.nosql.redis.connecting

Thanks, @breun! I was having a hard time finding this section in the docs. We should definitely link to this and also describe Memorystore-specific config in our refdoc.

I've created a pull request with information which would have helped me when I first had to set up a Spring Boot application for use with Cloud Memorystore: #2737

@breun Thank you! Please allow us some time to review the PR.
