Please revert this change.
This repo has two binaries which are built, WMCO and WICD.
Each should have their own subdirectory under cmd/.

I don't see any changes related to https://book.kubebuilder.io/migration/manually_migration_guide_gov3_to_gov4#update-kustomize-manifests-with-the-changes-made-so-far, please ensure this is handled.

So the change that the update mentioned is that it's no longer using kustomizev2alpha, which we don't implement anywhere
The changes it's recommending are to be sure that there's no scaffolding updates, but between v3 and v4 in the example, there doesn't seem to be any, and our structure is pretty much the same as the v4 example. I don't think these updates apply to us.

[mansikulkarni96]

https://book.kubebuilder.io/migration/manually_migration_guide_gov3_to_gov4 mentions following change to the layout:
The controller(s) directory has been moved under a new directory called internal and renamed to singular as well controller

[mansikulkarni96]

You can use https://github.com/kubernetes-sigs/kubebuilder/tree/master/testdata/project-v4 to compare the scaffolding structure between v3 and v4.
Note: mention if you ran any commands in the commit message after you made the changes.

I think the kustomize v3 to v4 changes still need to be done -- there's Makefile, go.mod, and config/ dir differences between v3 and v4
