Add redis/valkey clusters to gitlabci testing

Problem/Motivation

Add the ability for tests to run against a redis cluster, through envoy.

Steps to reproduce

Tests should run normally, but with additional cluster tests

Proposed resolution

Adding cluster setup tasks/templates and running existing tests against envoy connection

Remaining tasks

Testing, ironically

Did some initial work on this and pushing it to an issue fork. I need to wire up a way to actually test this because I 100% think there will be some odd race issues with the standup, based on doing this with ddev. This is somewhat based on the ddev plugin, but with both a valkey and redis version. Possibly don't want that as it may really slow down the testing process, but for now they are both here.
