[SPARK-18448][CORE] SparkSession should implement java.lang.AutoCloseable
like JavaSparkContext
## What changes were proposed in this pull request?
Just adds `close()` + `Closeable` as a synonym for `stop()`. This makes it
usable in Java in try-with-resources, as suggested by @ash211 (`Closeable`
extends `AutoCloseable` BTW)
## How was this patch tested?
