R and SparkR Support [WIP]
### What is this PR for?
Implement R and SpakR Intepreter as part of the Spark Interpreter Group. It
also implements R and Scala binding (in both directions).
### What type of PR is it?
[Feature]
### Todos
* [ ] - Documentation
* [ ] - Unit test (if relevant, as we depend on R being available on the
host)
* [ ] - Assess licensing (a priori ok as we don't delive anything out of
ASL2, but we should corectly phrase the NOTICE as we depend on non-ASL2
comptabile licenses (R) to run the interpreter).
### Is there a relevant Jira issue?
https://issues.apache.org/jira/browse/ZEPPELIN-156 SparkR support
### How should this be tested?
You need R available on the host running the notebook.
For Centos: yum install R R-devel
For Ubuntu: apt-get install r-base r-cran-rserve
Install additional R packages:
```
curl
https://cran.r-project.org/src/contrib/Archive/rscala/rscala_1.0.6.tar.gz -o
/tmp/rscala_1.0.6.tar.gz
R CMD INSTALL /tmp/rscala_1.0.6.tar.gz
R -e "install.packages('ggplot2', repos = 'http://cran.us.r-project.org')"
R -e install.packages('knitr', repos = 'http://cran.us.r-project.org')
```
- Build + launch Zeppelin and test the R note.
!!! you need rscala_1.0.6 (if not, you need to build with
-Drscala.version=...)

### Questions:
* Does the licenses files need update? to be checked... (cfr R needs to be
available to make this interpreter operational).
* Is there breaking changes for older versions? No
* Does this needs documentation? Yes
