cfq-iosched: Implement tunable group_idle
o Implement a new tunable group_idle, which allows idling on the group
instead of a cfq queue. Hence one can set slice_idle = 0 and not idle
on the individual queues but idle on the group. This way on fast storage
we can get fairness between groups at the same time overall throughput
improves.
