improve kind installation page

[craigbox]

https://istio.io/latest/docs/setup/platform-setup/kind/

The new target audience for this page is a Getting Started user.

We should rewrite:

• to not need to know about your Go version
• s/MetalLB/Cloud Provider kind/, and only if you really need it
• without concern for the Kubernetes Dashboard

and/or we should use Minikube instead.

Honestly, this page has nothing Istio specific, and no special configuration/setting is needed to run Istio on kind (in this case).

Why don't we get rid of this page and just say "Visit kind.sh for instructions on how to set up your cluster" where applicable. If platforms require some special Istio-specific setup/config then we should call that out.

[peterj]

A couple of common themes across all platforms:

• run a cluster large enough to run Istio + bookinfo (e.g. 8gb mem requirement from docker desktop, minikube, etc.)
• different ways of exposing ingress gateway, getting the IP, etc.

Other than that, the instructions are not in any way specific to Istio and they are mostly about setting up a k8s cluster.

Platform	Notes
Alibaba cloud	Outdated (i.e. "hasn't been tested on 1.9") + no Istio specific config
Amazon EKS	no Istio specific config, links to EKS blueprints
Azure	no Istio specific config
Docker Desktop	no Istio specific config
GKE	Has a note for private GKE cluster + section for multi-cluster communication (which isn't necessarily istio specific)
Huawei	Notes on resources, but otherwise no Istio specific config
IBM	no Istio specific config
k3d	command to set up a k3d cluster without traefik and to expose certain ports (I think)
kind	no Istio specific config
Kops	no Istio specific config (unless you're k8s < 1.22)
Kubernetes Gardener	no Istio specific config
KubeSphere Container Platform	Outdated (i.e. "hasn't been tested on 1.9") + no Istio specific config
MicroK8s	no Istio specific config
Minikube	Memory requirements, no Istio specific config
Openshift	no Istio specific config
OCI	Outdated, no Istio specific config
Tencent	no Istio specific config

I think these 18 subpages could be links to instructions on the platforms' website for setting up the cluster.

I've been wanting to collapse these down to one page. Let's do that.

[peterj]

All right, I'll collapse this down.

[peterj]

Before I go further down the hole, would the FAQ layout work well for this page, @craigbox?

[craigbox]

Maybe? Depends how big the titles are under each section, I guess.
Hopefully it's just a small toggle to change each and we'll see what they look like

[peterj]

https://github.com/istio/istio.io/pull/15425 changes the page to FAQ-style.

@craigbox should I go ahead and remove all instructions that don't have any Istio specific steps? (or do we keep it around for SEO purposes perhaps)
