Balazs Gibizer 53ca096750 consumer gen: move_allocations ... This patch renames the set_and_clear_allocations function in the scheduler report client to move_allocations and adds handling of consumer generation conflict for it. This call now moves everything from one consumer to another and raises AllocationMoveFailed to the caller if the move fails due to consumer generation conflict. When migration or resize fails to move the source host allocation to the migration_uuid then the API returns HTTP 409 and the migration is aborted. If reverting a migration, a resize, or a resize to same host fails to move the source host allocation back to the instance_uuid due consumer generation conflict the instance will be put into ERROR state. The instance still has two allocations in this state and deleting the instance only deletes the one that is held by the instance_uuid. This patch logs an ERROR describing that in this case the allocation held by the migration_uuid is leaked.
