zhanghailiang 479125d53e COLO: fix setting checkpoint-delay not working properly
If we set checkpoint-delay through command 'migrate-set-parameters',
It will not take effect until we finish last sleep chekpoint-delay,
That's will be offensive espeically when we want to change its value
from an extreme big one to a proper value.

Fix it by using timer to realize checkpoint-delay.
