[SPARK-19558][sql] Add config key to register QueryExecutionListeners
automatically.
This change adds a new SQL config key that is equivalent to SparkContext's
"spark.extraListeners", allowing users to register QueryExecutionListener
instances through the Spark configuration system instead of having to
explicitly do it in code.
The code used by SparkContext to implement the feature was refactored into
a helper method in the Utils class, and SQL's ExecutionListenerManager was
modified to use it to initialize listener declared in the configuration.
Unit tests were added to verify all the new functionality.
