cgroup: notify ns_cgroup deprecated
The ns_cgroup will be removed very soon. Let's warn, for this version,
ns_cgroup is deprecated.
Make ns_cgroup and clone_children exclusive. If the clone_children is set
and the ns_cgroup is mounted, let's fail with EINVAL when the ns_cgroup
subsys is created (a printk will help the user to understand why the
creation fails).
Update the feature remove schedule file with the deprecated ns_cgroup.
