Title: should call reviveOffer in fine-grained mesos mode after tasks successfully finished 

I think we should call reviveOffer in statusUpdate function to request resource, In scheduler.statusUpdate function, it calls reviveOffer only for TASK_LOST and TASK_FAILED, so it need deal with TASK_FINISHED scenario, this improvement will enhance performance significantly.
