migration: Enter into COLO mode after migration if COLO is enabled
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.
