[SPARK-24433][K8S] Initial R Bindings for SparkR on K8s
## What changes were proposed in this pull request?
Introducing R Bindings for Spark R on K8s
- [x] Running SparkR Job
## How was this patch tested?
This patch was tested with
- [x] Unit Tests
- [x] Integration Tests
## Example:
Commands to run example spark job:
1. `dev/make-distribution.sh --pip --r --tgz -Psparkr -Phadoop-2.7 -Pkubernetes`
2. `bin/docker-image-tool.sh -m -t testing build`
3.
```
bin/spark-submit \
--master k8s://https://192.168.64.33:8443 \
--deploy-mode cluster \
--name spark-r \
--conf spark.executor.instances=1 \
--conf spark.kubernetes.container.image=spark-r:testing \
local:///opt/spark/examples/src/main/r/dataframe.R
```
This above spark-submit command works given the distribution. (Will include
this integration test in PR once PRB is ready).
