• Support NVIDIA MIG for more secure multi-tenant GPU sharing / allocation bottlerocket#4252

Description of changes:
Adding nvidia-migmanager service and binary that configures the instance with nvidia mig.

Testing done:

1. Instance joined the cluster

NAME                                           STATUS   ROLES    AGE   VERSION
ip-XXXX.us-west-2.compute.internal   Ready    <none>   15h   v1.29.5-eks-1109419

2. Model Default:

bash-5.1# apiclient get settings.kubelet-device-plugin
{
  "settings": {
    "kubelet-device-plugins": {
      "nvidia": {
        "device-id-strategy": "index",
        "device-list-strategy": "volume-mounts",
        "device-partitioning-strategy": "none",
        "device-sharing-strategy": "none",
        "pass-device-specs": true
      }
    }
  }
}

3. Model Updates:

bash-5.1#: apiclient set settings.kubelet-device-plugins.nvidia.device-partitioning-strategy="mig"
bash-5.1#: apiclient set settings.kubelet-device-plugins.nvidia.mig.profile-a100="1g.5gb"
bash-5.1# apiclient get settings.kubelet-device-plugin
{
  "settings": {
    "kubelet-device-plugins": {
      "nvidia": {
        "device-id-strategy": "index",
        "device-list-strategy": "volume-mounts",
        "device-partitioning-strategy": "mig",
        "device-sharing-strategy": "none",
        "mig": {
          "profile-a100": "1g.5gb"
        },
        "pass-device-specs": true
      }
    }
  }
}

kubectl describe node shows 56 gpus post instance reboot.

bash-5.1# apiclient set settings.kubelet-device-plugins.nvidia.mig.profile-a100="1g.10gb"
