[SPARK-20722][Core][History Server] Replay newer event log that hasn't be
replayed in advance for request
## What changes were proposed in this pull request?
History server may replay logs slowly if the size of event logs in current
checking period is very large. It will get stuck for a while before entering
next checking period, if we request a newer application history ui, we get the
error like "Application application_1481785469354_934016 not found". We can let
history server replay the newer event log in advance for request.
