Hi Paul

I think this flavor bp is related.
https://review.openstack.org/#/c/90070/
By using flavor, you can specify the flavor for routers ( high
bandwidth or low bandwidth ) such as VM (vCPU vMemory etc).
I don't see any bp for flavor based scheduling yet, but IMO it is
great we could have such scheduler such as
Nova's filter scheduler.
