Hi Abbass, I am in the process of coding some of this now - take a look at
https://blueprints.launchpad.net/nova/+spec/extensible-resource-tracking - now has a specification document attached https://etherpad.openstack.org/p/IcehouseNovaExtensibleSchedulerMetrics - the design summit session on this topic see what you think and feel free to comment - I think it covers exactly what you describe.
