1G hugepages are only available in following machine familes: c3, m2,
c2d, c3d, h3, m3, a2, a3, g2.
Supported values for 'cgroupMode' under 'linuxConfig'.
◆ CGROUP_MODE_V1: Use cgroupv1 on the node pool.
◆ CGROUP_MODE_V2: Use cgroupv2 on the node pool.
◆ CGROUP_MODE_UNSPECIFIED: Use the default GKE cgroup configuration.
Note, updating the system configuration of an existing node pool
requires recreation of the nodes which which might cause a disruption.
