Bug Description

Currently we are using the raw values directly from the available weighers, instead of normalizing them. This makes difficult to properly use multipliers for establishing the relative importance between two weighters (one big magnitude will shade a smaller one).

Nova is now adding this feature and this was already finished for base weight class, so we can port this feature to Oslo to be leveraged by other projects: https://blueprints.launchpad.net/nova/+spec/normalize-scheduler-weights

Also, porting this feature to Nova can enable nova use Oslo scheduler later: https://blueprints.launchpad.net/nova/+spec/nova-oslo-scheduler
