blkio: Implement per cfq group latency target and busy queue avg
o So far we had 300ms soft target latency system wide. Now with the
introduction of cfq groups, divide that latency by number of groups so
that one can come up with group target latency which will be helpful
in determining the workload slice with-in group and also the dynamic
slice length of the cfq queue.
