What's in this PR?

Migrates the operator to KubeBuilder go/v4 and operator-sdk v1.33.0, applying all appropriate migrations in the process. The migration process required re-scaffolding the entire API and all controllers in order to regenerate the PROJECT configuration, but the actual specs & controller code was copied forward. Regardless, care should be taken in reviewing this to ensure that i did not incidentally leave something out.

I updated the Makefile and all generated Kustomize configuration to match the latest in KubeBuilder. From this point, only minor updates should be required.

Primary changes:

• main.go moved to cmd/main.go
• controllers/ moved to internal/controller/
• All of the config/ generated yaml was updated

Note Merging this will necessitate updating your locally installed operator-sdk to v1.33.0.

Why?

KubeBuilder go/v4 is now stable and go/v3 will be end-of-lifed and removed.

Before taking an in-depth look and testing it, I think that the version of Operator SDK is mentionned in the documention (not sure for Kubebuilder itself), so it must be updated accordingly.

Yeah, so basically upgrading to operador-sdk v1.33.0 is just migrating to kubebuilder go/v4:

Initial checks LGTM.
I'll test a few cluster deployments using this branch tomorrow 👍

I was thinking of NiFiKop documentation 😄
