credit2: Track expected load

As vcpus are migrated, track how we expect the load to change.  This
helps smooth migrations when the balancing doesn't take immediate
effect on the load average.  In theory, if vcpu activity remains
constant, then the measured avgload should converge to the balanced
avgload.
