Feature: Updates project to latest operator-sdk version

Also updates the kubebuilder plugin to `go/v4` and updates files to use
the new project structure:

- Moves controller from `controllers` to `internal/controller`
- Moves modules from `pkg/modules` to `internal/modules`
- Moves `main.go` to `cmd/main.go`

This new version also removes support for `kube-rbac-proxy` and updates
multiple Kustomize manifests.

Also upgrades golang version to `v1.22.0`
