Kustomization - Generating a kustomization.yaml file

(I wanted to open a PR for this page, but did not find it in https://github.com/fluxcd/website).

I really would like to see two important facts in this page. And in the quickstart guide, but I'll open another issue for that.

• if no kustomization.yaml (Kubernetes, not the Flux2 one) is present, all manifests from all subdirectories are used.
• you can exclude manifests by using a kustomization.yaml that does not contain the manifests you want to exclude.

Something like this:

By default, Flux uses all manifests in the path specified by the Kustomization, if no kustomization.yaml is present. In this case a kustomization.yaml will be generated on the fly using all the manifests found in this directory and its subdirectories.

If a kustomization.yaml is found, only those manifests mentioned in it will be used. This is useful to exclude manifests or folders from being used, to e.g. use them in a separate kustomization due to ordering issues
