…lot clusters This update introduces a new `linux_cgroup_mode` variable to specify the cgroup hierarchy mode for autopilot Kubernetes nodes. Supported values include `CGROUP_MODE_UNSPECIFIED`, `CGROUP_MODE_V1`, and `CGROUP_MODE_V2`. Adjusted cluster configurations to include dynamic management of the Linux node configuration based on this variable.
Updated the condition block in `node_pools_cgroup_mode` validation across multiple variables files to use a more readable multi-line format.

Updated variable validation logic to use the `coalesce` function instead of conditional operators for `node_pools_cgroup_mode`, improving readability and consistency across modules.

Unfortunately Terraform doesn't short circuit evaluation, so you will need a try() around contains() for null handling.
