[SPARK-15703] [Scheduler][Core][WebUI] Make ListenerBus event queue size
configurable
## What changes were proposed in this pull request?
This change adds a new configuration entry to specify the size of the spark
listener bus event queue. The value for this config
("spark.scheduler.listenerbus.eventqueue.size") is set to a default to 10000.
Note:
I haven't currently documented the configuration entry. We can decide
whether it would be appropriate to make it a public configuration or keep it as
an undocumented one. Refer JIRA for more details.
## How was this patch tested?
Ran existing jobs and verified the event queue size with debug logs and
from the Spark WebUI Environment tab.
