Upgrade controller-runtime and Kubernetes API dependencies

What does this MR do?

This MR updates version of core dependencies:

• (sigs.k8s.io/controller-runtime)[https://pkg.go.dev/sigs.k8s.io/controller-runtime]
• Kubernetes API suit 0.29.3, including k8s.io/api and k8s.io/apimachinery as well as k8s.io/client-go and k8s.io/kubectl.

Also:

• sigs.k8s.io/controller-runtime (see release page) has a few breaking changes, in particular in manager.Options. The main.go is updated to match the new structure.
• The dependency to the obscure k8s.io/kube-openapi package is removed as well. The only function that was used from the dependency is copied over (see pkg/support/secrets/generator/tls_generator.go).

For details of breaking changes to namespace scope see:

• https://github.com/kubernetes-sigs/controller-runtime/pull/2421
• https://github.com/kubernetes-sigs/controller-runtime/pull/2422
