We will have a 'cgroups-per-qos' flag to specify if the user wants to use the QoS based cgroup hierarchy. The flag would be set to false by default at least in v1.4. We will have a 'experimental-cgroups-per-qos' flag to specify if the user wants to use the QoS based cgroup hierarchy. The flag would be set to false by default at least in v1.5.
