Regarding Production install, I think it is a good idea to provide context on the different types of helm charts that we provide, as well as the link to those helm charts (either the Core 2 repo charts in k8s/helm-charts or the helm-charts repo itself). Similar to how we used to have this here: https://docs.seldon.ai/seldon-core-2/getting-started/kubernetes-installation/helm

I left some comments on the current production install for Core 2. I think this is fine as a first cut, I suggest the following topics as follow up PRs:

• How to configure Core 2 installation via helm and what are the different settings that can be changed that are relevant to note. This is important in cases of resource allocations, tags, number of pods etc, mTLS etc.
• How to manage upgrade via helm. Upgrading Core 2 is perhaps a topic that needs more attention to document behaviour and provide options for a smooth upgrade.

Hi @paulb-seldon can we add these topics to the new IA so that we dont miss these suggestions.
