The <option>force</option> option will cause LXC to perform
the cgroup mounts for the container under all circumstances.
Otherwise it is similar to <option>cgroup-full:mixed</option>.
This is mainly useful when the cgroup namespaces are enabled
where LXC will normally leave mounting cgroups to the init
binary of the container since it is perfectly safe to do so.
