Google Distributed Cloud Updates Kubernetes to v1.35, Requires cgroupsv2

The latest update to Google Distributed Cloud (software only) for VMware brings a critical platform upgrade to Kubernetes version 1.35. This release introduces a fundamental change in resource management by requiring the use of `cgroupsv2`, marking the end of support for the older `cgroupsv1`. This means that any cluster creation or upgrade will fail if `cgroupsv1` is detected, with a preflight check actively blocking such operations. Customers currently utilizing Red Hat Enterprise Linux (RHEL) 7 or 8, which are configured to default to `cgroupsv1`, are specifically advised to manually enable `cgroupsv2` on their operating systems prior to initiating any upgrades. Failure to do so will prevent successful Kubernetes 1.35 deployments. Beyond the `cgroupsv2` requirement, this update also includes an upgrade of the container runtime, containerd, from version 2.0 to 2.1. Additionally, the underlying Ubuntu operating system image for all node types has been upgraded to version 24.04 for the 1.35.0-gke.525 release. During control plane and node pool upgrades, nodes will be automatically recreated with this new operating system image.
