[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``.
