Kubernetes 1.35 dropped cgroup v1 support. Adds unsupportedOSIDs to k8s 1.35 and latest test specs to exclude legacy OSes that still use cgroup v1 (amzn-20, centos-7x, ol-79, ubuntu-1804). This removes ~27 guaranteed failure instances per run, surfacing genuine kURL/product issues (yajl on Rocky, addon compatibility, etc.) instead of upstream-expected cgroup v1 failures. Files: - testgrid/specs/deploy.yaml: 5 k8s 1.35 tests updated - testgrid/specs/latest.yaml: 2 latest tests updated Refs: sc-137579

Problem
Kubernetes 1.35 dropped cgroup v1 support, but the TestGrid test specs still allow legacy OS distributions that exclusively use cgroup v1. This causes ~27 guaranteed failures per k8s 1.35 staging run, masking genuine kURL/product bugs.
Affected OSes (cgroup v1)
Expected Impact
