Kubelet Feature Gates from MD annotations are not going through

Hi
I have got a MachineDeployment object with metadata like this:
```
metadata:
annotations:
v1.kubelet-featuregates.machine-controller.kubermatic.io/DRAConsumableCapacity: "true"
v1.kubelet-featuregates.machine-controller.kubermatic.io/DRADeviceTaints: "true"
v1.kubelet-featuregates.machine-controller.kubermatic.io/DRAExtendedResource: "true"
v1.kubelet-featuregates.machine-controller.kubermatic.io/DRAPrioritizedList: "true"
v1.kubelet-featuregates.machine-controller.kubermatic.io/DynamicResourceAllocation: "true"
v1.kubelet-featuregates.machine-controller.kubermatic.io/ResourceHealthStatus: "true"
```

which is taken from Machine-Controller's code here https://github.com/kubermatic/machine-controller/blob/main/sdk/apis/cluster/common/consts.go#L181 but I cannot find any place where it would be used around here ? https://github.com/kubermatic/operating-system-manager/blob/main/pkg/controllers/osc/resources/operating_system_config.go#L465

am I overlooking something? Because the output kubeletConfig does NOT have these featuregates enabled or even templated in the output OSC.

Thanks
Ashley

Start in pkg/controllers/osc/resources/operating_system_config.go around the referenced line and trace how MachineDeployment annotations reach the generated OSC kubeletConfig. Compare that path with the feature-gate annotation constants in machine-controller's sdk/apis/cluster/common/consts.go. Reproduce the supplied annotations and consider the issue done when the resulting OSC contains the expected kubelet feature gates.
