[SPARK-20281][SQL] Print the identical Range parameters of SparkContext
APIs and SQL in explain
## What changes were proposed in this pull request?
This pr modified code to print the identical `Range` parameters of
SparkContext APIs and SQL in `explain` output. In the current master, they
internally use `defaultParallelism` for `splits` by default though, they print
different strings in explain output;
```
scala> spark.range(4).explain
== Physical Plan ==
*Range (0, 4, step=1, splits=Some(8))
scala> sql("select * from range(4)").explain
== Physical Plan ==
*Range (0, 4, step=1, splits=None)
```
## How was this patch tested?
Added tests in `SQLQuerySuite` and modified some results in the existing
tests.
