[SPARK-15489][SQL] Dataset kryo encoder won't load custom user settings ## What changes were proposed in this pull request? Serializer instantiation will consider existing SparkConf ## How was this patch tested? manual test with `ImmutableList` (Guava) and `kryo-serializers`'s `Immutable*Serializer` implementations. Added Test Suite. (If this patch involves UI changes, please attach a screenshot; otherwise, remove this) Author: Sela <ans...@paypal.com> Closes #13424 from amitsela/SPARK-15489.
