Newer controller-gen doesn't correctly recognize markers. Need upgrade.

**What would you like to be enhanced**:
Looks like the controller is still using 0.6.x controller-tools to manage markers. Controller-gen has a breaking change from 0.7 and the latest version is 0.11.x. This project need to upgrade markers to use newer controller-tools.
**Why is the change needed and what use case will it solve**:
This project is still using an old controller-tool version. It should be upgraded to work with newer controller-tools version.

Start by locating the controller-gen and controller-tools version references in the repository and review how marker generation is invoked. Upgrade the referenced tooling for the newer marker behavior, then verify that generation and the project checks still pass.
