This patch adds a new load consolidation strategy based on a heuristic
algorithm which focuses on measured CPU utilization and tries to
minimize hosts which have too much or too little load.
A new goal "vm_workload_consolidation" was added which executes
the strategy "VM_WORKLOAD_CONSOLIDATION".
This work depends on the implemetation of the bug:
