### What is this PR for?
Use shared test library versions in maven config so that lib versions do mot be fragmented.
Previously we used multiple versions of
- Junit (4.11, 4.12)
- mockito (1.9.0, 1.10.8, ...)
- powermock (...)
### What type of PR is it?

```
$ mvn org.apache.maven.plugins:maven-help-plugin:2.2:effective-pom | vim -
```
### Questions:
* Does the licenses files need update? - YES, I updated JUnit version to 4.12 from 4.11

### What is this PR for?
This PR is the first of two major steps needed to improve matplotlib integration in Zeppelin (ZEPPELIN-1344). The latter, which is a plotting backend with fully interactive tools enabled, will be done afterwards in a separate PR. This PR specifically for automatically displaying output from calls to matplotlib plotting functions inline with each paragraph. Thanks to the addition of post-execute hooks (ZEPPELIN-1423), there is no need to call any `show()` function to display an inline plot, just like in Jupyter.
### What type of PR is it?
Improvement
### Todos
The main code has been written and anyone who reads this is encouraged to test it, but there are a few minor todos:
- [x] - Add unit tests
- [x] - Add documentation
- [x] - Add screenshot showing iterative plotting with angular mode
### What is the Jira issue?
[ZEPPELIN-1345](https://issues.apache.org/jira/browse/ZEPPELIN-1345)
### How should this be tested?
In a pyspark or python paragraph, enter and run
``` python
import matplotlib.pyplot as plt
plt.plot([1, 2, 3])
```
The plot should be displayed automatically without calling any `show()` function whatsoever. A special method called `configure_mpl()` can also be used to modify the inline plotting behavior. For example,
``` python
z.configure_mpl(close=False, angular=True)
plt.plot([1, 2, 3])
```
allows for iterative updates to the plot provided you have PY4J installed for your python installation (which of course is always the case if you use pypsark). To clarify, this feature only currently works with pyspark (not python as there are no `angularBind()` and `angularUnbind()` methods yet). Doing something like:
```
plt.plot([3, 2, 1])
```
will update the plot that was generated by the previous paragraph by leveraging Zeppelin's Angular Display System. However, by setting `close=False`, matplotlib will no longer automatically close figures so it is now up to the user to explicitly close each figure instance they create. There's quite a bit more options for `z.configure_mpl()`, but I will save that discussion for the documentation.

### What is this PR for?
This PR is to automate release publish to maven repository.
We used to use maven-deploy-plugin and maven-release-plugin for release but somehow it didn't work well with Zeppelin so 0.5.5 and 0.5.6 haven't been published to maven repository.
Publishing release to maven repository will eventually help zeppelin to reduce binary package size by leading users to use Dynamic interpreter loading(#908).
Originally below modules were skipped for maven release
- all interpreters(except spark)
- zeppelin-display
- zeppelin-server
- zeppelin-distribution
on the other hand this pr will skip only:
- zeppelin-distribution
### What type of PR is it?

### Todos
- [x] Include SparkR/R interpreter in release

### What is this PR for?
Adding a python 2 &3 interpreter. It's a basic implementation (no py4j for example), with a java ProcessBuilder object used to instantiate a python REPL.
The interpreter doesn't bring it own python binary but uses the python specified by python.path configutation. Thus, you can still use your specific installed python modules (scikit-learn, matplotlib...) and the interpreter is able to work with python 2 & 3 without change.
I had a python helper function (zeppelin_show() ) to easily display matplotlib graph as SVG.
### What type of PR is it?
[Feature]
### Todos
* [x] - Code review
* [x] - Improve bootstrap.py : choose available helper functions and their names
* [x] - Unit / IT tests ?
* [x] documentation updates needed, that AhyoungRyu pointed out
* [X] LICENSE needs to be updated to include all non-apache licensed dependencies (i.e AFAIK Py4j is BSD ) in bin-license
* [x] double-check that code formatting conforms project style guide
* [x] the branch need to be rebased on latest master.

### How should this be tested?
1. In interpreter screen, in Python section, specify in python.path the python binary you want to use
2. In a paragraph, you can use the interpreter with **_%python_**. Calling help() will describe you the interpreter functionnalities.
3. Install py4j (pip install py4j) if you want to use input form
