sched/fair: Add cgroup_mode: tasks

Browse source

Since we are exploring this space; include a scheme that scales by total number
of runnable tasks. This results in:

	F_g_n' = M * F_g_n

This will obviously have: avg(F_g_n') > 1, (it will be ~M/N in fact).

And while that sounds odd, it actually has a fairly straight foward meaning for
"cpu.weight": average weight per member task.

This is an entirely valid and workable option, it is however wildly different
from the traditional meaning.

Included for completeness (and curiosity).
