[SPARK-25395][JavaAPI] Removing Optional Spark Java API ## What changes were proposed in this pull request? Previous Spark versions didn't require Java 8 and an ``Optional`` Spark Java API had to be implemented to support optional values. Since Spark 2.4 uses Java 8, the ``Optional`` Spark Java API should be removed so that Spark uses the original Java API. ## How was this patch tested? ``OptionalSuite`` class was removed to test Spark Java API ``Optional`` class (this class as well). Notice that the ``get`` method in the Spark Java API ``Optional`` class throws a ``NullPointerException`` when the value is not set whereas the native Java API ``java.util.Optional`` throws a ``NoSuchElementException``.
