Remove per-cgroup CPU allowance for RT tasks

Since we are removing CONFIG_RT_GROUP_SCHED kernel config option, the
CPU allowance for RT tasks is not controlled on per-cgroup bases anymore
and instead is configured globally. Currently we don't really use
per-cgroup allowance control for RT tasks and current implementation is
actually faulty (the allowance has to be shared by all the sibling
cgroups, so by setting all of them to 95% only the first one gets the
CPU share and the rest will actually fail).
Remove operations setting per-cgroup allowance.
