Add resource limits for the changed containers.

These five containers define CPU and memory requests but no CPU or memory limits. Add limits for every container in this DaemonSet, or document an approved exception. Set CPU limits high enough to avoid reintroducing the CFS throttling this change is intended to prevent.

As per path instructions: Kubernetes/OpenShift manifests require cpu and memory limits on every container.

Add CPU and memory limits to every container in the DaemonSet, including the
containers at the referenced resource sections, while retaining their existing
requests. Choose CPU limits high enough to avoid reintroducing CFS throttling
and ensure no container lacks either required limit; document an approved
exception instead only if a limit cannot be provided.

Add the required bindata template test.

No corresponding *_test.go change is included in the reviewed cohort. Add a render test that asserts the five CPU requests, or document a valid exception.

As per coding guidelines: bindata/**/*.{yaml,yml} changes require corresponding *_test.go files to be added or modified unless a documented valid exception applies.

Add or update the corresponding bindata render test for the ovnkube-node
template to assert all five CPU request values, including the entries
represented by the changed cpu fields. If a render test cannot be added,
document the valid exception according to the repository’s guidelines.
