[A clear and concise description of what you want to happen.]

In the ODLM, there are some duplicate codes for similar functions.
For example:

• finalizer management
• status initialization
• code structuration like createIfNotExists, createOrUpdate and deleteIfExits.

Anything else you would like to add:
[Miscellaneous information that will assist in solving the issue.]

We can abstract an ODLM controller for managing common functions like finalizer management #517 and using provided API from controller-runtime https://pkg.go.dev/sigs.k8s.io/[email protected]/pkg/controller/controllerutil for createIfNotExists, createOrUpdate and deleteIfExits.
