Document use of kind tool for developer k8s cluster deployments

[mrutkows]

Feature request

This issue is being opened assure work is done on a suggested follow-on PR to add developer documentation related to use of kind (i.e., https://kind.sigs.k8s.io/) and leverage existing scripts perhaps to deploy Tekton into K8s clusters.

See discussion in: #3955

Specifically, what was suggested by @afrittoli and endorsed by @nikhil-thomas and @sbwsg is copied here:

@afrittoli also has an extremely useful script for getting a Kind cluster installed with the latest version tekton pipelines running inside it.

Indeed, I find kind to be great for development. With KO_DOCKER_REPO=kind.local the images built by ko are uploaded directly into the containerd cache, which is very convenient.

The script is in the plumbing repo.
I also have an evolution of that which includes setting up an ingress controller and more, but I need to clean it up before I can put it back into plumbing.

I wonder if something like that would be useful as an "extremely quick quickstart"? We could place in contrib/ and reference it from here. Not a blocker on this PR though at all.

Agreed, linking the kind script in here could be an extra PR on top.

Note: I would happily agree to own this as I was unaware of kind and welcome the opp. to learn about this.

Use case

Assist developers in standing up k8s clusters not specific to any provider/platform

Sooo the plan is to document the kind tool and specifically leverage the use of this script:
https://github.com/tektoncd/plumbing/blob/main/hack/tekton_in_kind.sh

IMO, we should also document the script purpose/usage not only in DEVELOPMENT.md, but also in a new README in the parent "plumbing/hack" directory (and see if we can leverage that as a canonical doc. from DEVELOPMENT.md".

I can work to do these things as well as as test it in at least Docker Desktop... perhaps it might surface other parameters that the script could take in as well? Looking forward.
