Migration/colo.c: Add new COLOExitReason to handle all failover state

Browse source 
In this patch we add the processing state for COLOExitReason,
because we have to identify COLO in the failover processing state or
failover error state. In the way, we can handle all the failover state.
We have improved the description of the COLOExitReason by the way.
