Switch kudo controller installation from kustomize to go templates and introduce kudo init

[alenkacz]

What would you like to be added:
Right now we have configs for kudo controller installation in config/crds and config/default where the second one using kustomize to derive the final yaml from templates. My proposal would be to switch to go templates or whatever helm uses (I think we don't need strategic merge patching here) and introduce kudo init printing out the output yaml.

As a next step, we can easily introduce helm chart for kudo and add it to the main repo.

Why is this needed:
It would simplify kudo installation into cluster a lot.

I think the kustomization is obsolete and init is in place
