> When I using the REST API of the AHS to get a running app's latest attempt id, it always
returns a invalid id like *appattempt_1516873125047_0013_{color:#FF0000}-000001{color}*. 
> But when the app is finished, the RM will push a finished event which contains the latest
attempt id to TimelineServer, so the id will transitive to a correct one in the end of the
application. 
> I think as the app is running, this value should be a correct one, so I add the latest
attempt id in the other info of the app's entity when the app trans to RUNNING state. Then
the AHS will use this value to set the currentAppAttemptId.
