Test custom AMI for EFA support

[mikkeloscar]

This PR is purely for enabling testing of an in-progress AMI to enable support for EFA on g5 instances.

The idea is that a cluster switched to this PR branch will be able to run a node-pool like this:

- config_items:
    labels: dedicated=gpu-g5-efa,zalando.org/nvidia-gpu=nvidia-a10g
    taints: dedicated=gpu-g5-efa:NoSchedule
    kuberuntu_distro_worker: "jammy_with_gpu"
    tag_instance_infrastructure_component: "false"
  discount_strategy: none
  instance_types:
  - g5.8xlarge
  - g5.12xlarge
  - g5.16xlarge
  - g5.24xlarge
  - g5.48xlarge
  max_size: 30
  min_size: 0
  name: gpu-g5-efa
  profile: worker-karpenter

With will run the special AMI defined as: kuberuntu_image_v1_31_jammy_with_gpu_amd64. To change the AMI to test, only that config-item needs to be changed in this PR and the node pool will be updated.
