https://review.openstack.org/#/c/290534/ was reverted as it did not work in the case where the node running the scheduler is also a compute node. As cpu_allocation_ratio, ram_allocation_ratio and disk_allocation_ratio can all be set on the scheduler node and/or overridden on the compute node level, it makes sense to move these parameters to the top level.
