Unified Migrations

Registered by Dan Smith

Resize/Migrate/LiveMigrate/Rebuild are all separate code paths. They should be unified to share as much of the same code as possible, as right now they do not. The overwhelming consensus is that coordination of the migrations should be moved to conductor, where we can eventually eliminate the migration state living on the compute nodes and the implicit trust between compute nodes required to pull off a migration.
