Gabor Somogyi f83000597f [SPARK-23472][CORE] Add defaultJavaOptions for driver and executor. ... ## What changes were proposed in this pull request? This PR 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 (default options are prepended to extra options). ## How was this patch tested? Existing + additional unit tests. ``` cd docs/ SKIP_API=1 jekyll build ``` Manual webpage check. Closes #24804 from gaborgsomogyi/SPARK-23472.
