sched: Tighten controls for tasks spillover to idle cluster
Several conditions can cause an idle cluster to pick up load from a
busy cluster. One such condition is when busy cluster has number of
tasks that exceeds its capacity (or number of cpus). This patch
extends that condition to consider small and big tasks on a cluster.
Too many "small" tasks should not cause them to spill over to another
idle cluster. Like-wise presence of big tasks should be considered
by a cluster to pick up load from another another cluster with lower
capacity.
