sched: Add USER_SCHED to feature removal list 

Peter Zijlstra suggested that we remove USER_SCHED at:

   http://lkml.org/lkml/2009/3/21/67

Removing USER_SCHED removes a lot of code from the scheduler
and simplifies the code.

We already have the ability to do user based classification
which is tightened using PAM in userspace.

Schedule USER_SCHED for removal in 2.6.34

---------------------------
What: USER_SCHED
When: 2.6.34
Why: USER_SCHED was implemented as a proof of concept for group scheduling.
The effect of USER_SCHED can already be achieved from userspace with
the help of libcgroup. The removal of USER_SCHED will also simplify
the scheduler code with the removal of one major ifdef. There are also
issues USER_SCHED has with USER_NS. A decision was taken not to fix
those and instead remove USER_SCHED. Also new group scheduling
features will not be implemented for USER_SCHED.
