[ZEPPELIN-1604] Add Neo4j interpreter and Network visualization
### What is this PR for?
This contribution would to introduce Neo4j Cypher intepreter and the new
network visualization;
at the same time would provide base APIs that enable other graph databases
(or graph framworks such as GraphX or Giraph).
### What type of PR is it?
[Feature]
### Todos
* [x] - Create the network visualization
* [x] - Provide base APIs to manage graph results (under:
org.apache.zeppelin.interpreter.graph.*)
* [x] - Create the Neo4j intepreter
### What is the Jira issue?
[[ZEPPELIN-1604]](https://issues.apache.org/jira/browse/ZEPPELIN-1604)
### How should this be tested?
Donwload and execute [Neo4j](https://neo4j.com/download/?ref=home) v3.x,
you can also pull a [Docker image](https://neo4j.com/developer/docker/).
In order to execute test cases, if you are running Java 7, you need to also
provide an environment variable telling the tests where to find Java 8, because
Neo4j-the-database needs it to run.
```bash
export NEO4J_JAVA=<path/to/java/home>
```
Use this statement to create a dummy dataset
```bash
%neo4j
UNWIND range(1,100) as id
CREATE (p:Person {id:id, name: "Name " + id, age: id % 3}) WITH collect(p)
as people
UNWIND people as p1
UNWIND range(1,10) as friend
WITH p1, people[(p1.id + friend) % size(people)] as p2
CREATE (p1)-[:KNOWS {years: abs(p2.id - p2.id)}]->(p2)
```
Then you can write some simple queries like:
```bash
%neo4j
MATCH (p:Person)-[r:KNOWS]-(p1:Person)
RETURN p, r, p1
LIMIT 10;
```
```bash
%neo4j
MATCH (p:Person)-[r:KNOWS]-(p1:Person)
RETURN p.id AS ID_A, p.name AS NAME_A, r.years AS YEARS, p1.id AS ID_B,
p1.name AS NAME_B
LIMIT 20;
```
### Screenshots
### Video
### Questions:
* Does the licenses files need update? **Yes**
* Is there breaking changes for older versions? **No**
* Does this needs documentation? **Yes**. I have create the neo4j.md file
in /docs/intepreter folder
