cgroups isn't really the schedular here - its just the mechanism for
supplying the cpu_shares parameter to the schedular.
I sort of imagined that for Linux based VMs we'd key this off the
various schedulars available for sched_getscheduler(2), but
actually thinking about it more, its probably best to just say that
the schedular is 'posix', and make the choice of SCHED_FIFO,
SCHED_RR, SCHED_OTHER, etc be a tunable parameter.
