cgroups: make cgroup config a submenu

Making CGROUP related configs be a sub-menu.

This patch make CGROUP related configs be a sub-menu and makes 1st level
configs of "General Setup" shorter.

 including following additional changes
  - add help comment about CGROUPS and GROUP_SCHED.
  - moved MM_OWNER config to the bottom.
    (for good indent in menuconfig)

This feature lets CPU scheduler recognize task groups and control CPU
bandwidth allocation to such task groups.
In order to create a group from arbitrary set of processes, use

This feature lets you explicitly allocate real CPU bandwidth
to users or control groups (depending on the "Basis for grouping tasks"

schedule realtime tasks for non-root users until you allocate
realtime bandwidth for them.
