-`G` pods will be placed at the `$Root` cgroup by default. `$Root` is the system root ie. "/" by default and if `--cgroup-root` flag is used then we use the specified cgroup-root as the `$Root`. To ensure Kubelet's idempotent behaviour we follow a pod cgroup naming format which is opaque and deterministic.

 __Note__: The cgroup-root flag would allow the user to configure the root of the QoS cgroup hierarchy. Hence cgroup-root would be redefined as the root of QoS cgroup hierarchy and not containers.

 - We have a top level QoS cgroup for the `Bu` and `BE` QoS classes.
 - But we __dont__ have a separate cgroup for the `G` QoS class. `G` pod cgroups are brought up directly under the `Root` cgroup.
 - Each pod has its own cgroup which is nested under the cgroup matching the pod's QoS class.
