colo: make colo_checkpoint_notify static and provide simpler API
colo_checkpoint_notify() is mostly used in colo.c. Outside we use it once when x-checkpoint-delay migration parameter is set. So, let's simplify the external API to only that function - notify COLO that parameter was set. This make external API more robust and hides implementation details from external callers. Also this helps us to make COLO module optional in further patch (i.e. we are going to add possibility not build the COLO module).
