This is what I see in zeppelin and jupyter. The difference is due to zeppelin also add code completion of ace editor. I think code completion of ace editor should only be enabled when the backend interpreter doesn't support completion.

### What is this PR for?
**First of all, this PR doesn't affect on runtime application behaivor and existing build processes. Just abstracting variables in pom.xml**
The main goal of this PR is bringing consistency and maintainability in all pom.xml. I referred these 2 projects.
- [apache/spark: pom.xml](https://github.com/apache/spark/blob/master/pom.xml)
- [apache/storm: pom.xml](https://github.com/apache/storm/blob/master/pom.xml)
Currently, all libraries and plugins have duplicated version fields since we are not using `dependencyManagement`, `pluginManagement` efficiently in pom.xml
This results in
- unmanaged plugin, library versions (someone might update only a child's library version. it happend in our pom.xml files)
- so many duplicated code blocks (bad)
- fragmented plugin, library versions (some project uses junit 4.11 while another uses 4.12)
These are some examples
```xml
// hard coded, non consistent version management
<dependency>
<groupId>org.apache.thrift</groupId>
<artifactId>libthrift</artifactId>
<version>${libthrift.version}</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
<version>4.3.3</version>
</dependency>
```
```xml
// a/pom.xml
<plugin>
<artifactId>maven-enforcer-plugin</artifactId>
<version>1.3.1</version>
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.8</version>
// b/pom.xml
<plugin>
<artifactId>maven-enforcer-plugin</artifactId>
<version>1.3.1</version>

### What type of PR is it?
[Refactoring]
### Todos

### What is the Jira issue?
[ZEPPELIN-1695](https://issues.apache.org/jira/browse/ZEPPELIN-1695)
### How should this be tested?
Since this PR doesn't affect runtime behavior at all, CI test would be enough.
### Questions:
* Does the licenses files need update - NO
* Is there breaking changes for older versions - NO

### What is this PR for?
This PR enables edit on double click for markdown/angular paragraph. Users can change `editOnDblClick` field to be `false` by editting `interpreter/md/interpreter-setting.json` or `conf/interpreter.json`. In the same context, users can set other type paragraphs to be editable on double click by setting `editOnDblClick` to be true.
This PR also fixes bug that syntax highlight doesn't work on pasted code.

### 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 is this PR for?
When people implement a new interpreter, they extend [interpreter.java](https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/main/java/org/apache/zeppelin/interpreter/Interpreter.java) as described in [here](https://zeppelin.apache.org/docs/0.6.0-SNAPSHOT/development/writingzeppelininterpreter.html). Among the several methods in [interpreter.java](https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/main/java/org/apache/zeppelin/interpreter/Interpreter.java), [completion API](https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/main/java/org/apache/zeppelin/interpreter/Interpreter.java#L109) enables auto-completion.
However this API is too simple compared to other project's auto-completion and hard to add more at the moment. So for the aspect of further expansion, it would be better to separate and restructure this API before the this release( 0.6.0 ).
### What type of PR is it?
Improvement
### Todos
* [x] - Create new structure : `InterpreterCompletion` in `RemoteInterpreterService.thrift` and regenerate `zeppelin-interpreter/src/main/java/org/apache/zeppelin/interpreter/thrift/*` files
* [x] - Change all existing `List<String> completion` -> `List<InterpreterCompletion> completion`
* [x] - Change `paragraph.controller.js` to point real `name` and `value`
### What is the Jira issue?
[ZEPPELIN-982](https://issues.apache.org/jira/browse/ZEPPELIN-982)
### How should this be tested?
Since this improvement is just API change, it should work same as before. So after applying this patch, and check whether auto-completion works well or not.
Use `. + ctrl` for auto-completion. For example,
```
%spark
sc.version
```
When after typing `sc.` and pushing `. + ctrl` down, `version` should be shown in the auto-completion list.

Here's a short video demo of this feature.
[](http://www.youtube.com/watch?v=xU5TBS_MsAs)
for someone who want to try, here's api
```scala
// bind 'varName' variable with 'v' value
z.angularBind(varName: String, v: Object)
// unbind 'varName'
z.angularUnbind(varName: String)
// get value of 'varName'
z.angular(varName:String)
// add watcher to 'varName' variable.
// that is monitoring change and run 'func' when it is changed.
z.angularWatch(varName:String, func: (Object, Object) => Unit))
// remove watcher from 'varName'
z.angularUnwatch(varName:String)
```
Any paragraph's output starting with '%angular' will be considered as angular code. %angular as a interpreter also available.
Any feedback is welcome!
