Support for multiple active scheduler drivers
In heterogenous environments, it might be desirable to apply different scheduling policies in different host aggregates. This could be different drivers, or even same driver with different configurations (e.g., FilterScheduler with different sets of filters/weights and/or different parameters of particular filters/weights).
[Details in the wiki have been updated to reflect the proposed design for Icehouse]

Add db api to get aggregate by key value
Its a bit late in Icehouse to merge this, the performance risk seems really high. We need to cut some blueprints, and I am afraid this one has been chosen. Certainly worth pushing back up when Juno opens. Need to take some care about not affecting the peformance of the faster, but less feature-full path --johnthetubaguy
Unapproved - please re-submit via nova-spec --johnthetubagy (20th March 2014)Gerrit topic: https:/
