Conductor: Initial Move Cold Migrations To Conductor work

Registered by Dan Smith on 2013-04-25

Regular resize/migrate functions should move to conductor to set out the path for the other migrate-related functions and how they will co-exist. Also to define how conductor will drive these processes without state in the compute nodes.

Apologies, this missed the deadline for Feature Freeze. Marking this one as Implemented, so please open a new blueprint for the remaining patches. Please rebase patches as soon as Juno opens, and we will try to get this in during that period. --johnthetubaguy (5th March 2014)
