[SPARK-8019] [SPARKR] Support SparkR spawning worker R processes with a
command other then Rscript
This is a simple change to add a new environment variable
"spark.sparkr.r.command" that specifies the command that SparkR will
use when creating an R engine process. If this is not specified,
"Rscript" will be used by default.
I did not add any documentation, since I couldn't find any place where
environment variables (such as "spark.sparkr.use.daemon") are
documented.
I also did not add a unit test. The only test that would work
generally would be one starting SparkR with
sparkR.init(sparkEnvir=list(spark.sparkr.r.command="Rscript")), just
using the default value. I think that this is a low-risk change.
