Bug Fix: LiveListenerBus Queue Overflow
As we know, the size of "eventQueue" is fixed. When event comes faster
than consume speed of listener, overflow events will be thrown away with
throwing an "logQueueFullErrorMessage'. As a result, we find spark UI in
chaotic state. In my Strategy, those overflow events are "cached" in
"blockManager" first , and replayed by "replayThread" when "eventQueue" is
free. The unique drawback is some display delay in Spark UI. But it is better
than event loss. This delay will disappear when event stress alleviates.
