Migrate redis-registry-cache to VM's/Chef

In 2022 we pursued deploying Redis Sentinel in Kubernetes. First we created a greenfields deployment redis-registry-cache in &619. In &782 we tried moving redis-ratelimiting, an existing high traffic Redis Sentinel cluster, to K8s. We were not happy with the results and at the end of &782 we concluded not to invest more time in this idea. We kept redis-ratelimiting on VM's. We are now spending time trying to make Redis Cluster work in &823.

For the sake of uniformity, I propose that we migrate redis-registry-cache to a VM/Chef setup like all our other Redis Sentinel deployments. As long as everything works there is no problem, but the moment we need to change, investigate or fix something we end up investing time in a platform we don't know well (Redis+K8s) and that we consider a dead end.
