As agreed in the spec, we want to provide to the scheduler the possible destination asked by the admin when calling evacuate or live-migrate. Adding a possibility to default the field to None if an old RequestSpec or a legacy dict wants to hydrate. Change-Id: I6ddcaaca37fc5387c2d2e9f51c67ea9e85acb5c5 Partially-Implements: blueprint check-destination-on-migrations-newton
