Add a new migration state: MIGRATION_STATUS_COLO. Migration source side enters this state after the first live migration successfully finished if COLO is enabled by command 'migrate_set_capability x-colo on'. We reuse migration thread, so the process of checkpointing will be handled in migration thread.
