[SPARK-12792][SPARKR] Refactor RRDD to support R UDF.
Refactor RRDD by separating the common logic interacting with the R worker
to a new class RRunner, which can be used to evaluate R UDFs.
Now RRDD relies on RRuner for RDD computation and RRDD could be reomved if
we want to remove RDD API in SparkR later.
