SPARK-23472: Add defaultJavaOptions for drivers and executors.
## What changes were proposed in this pull request?
This adds two new config properties: spark.driver.defaultJavaOptions and
spark.executor.defaultJavaOptions. These are intended to be set by
administrators in a file of defaults for options like JVM garbage collection
algorithm. Users will still set `extraJavaOptions` properties, and both sets of
JVM options will be added to start a JVM. Otherwise, it is difficult for
administrators to add properties that are not clobbered when users change their
JVM options.
## How was this patch tested?
We have had this deployed to production for several weeks. If there is a
place to add command-line options tests, please let me know and I'll add them.
