GKE is deprecating cgroupv1

On September 16, 2024 cgroupv1 API was deprecated in GKE 1.31.
Starting February 15, 2025 Clusters using cgroupv1 API will be automatically upgraded to cgroupv2 on GKE 1.32.
Starting December 15, 2025 cgroupv1 API will reach end of life in GKE version 1.33 (or later).

We have a hard dependency on cgroupv1 for our kind setup. We need a v2 solution

Another thread claims it Just Works now with kind, so maybe this just needs testing
