[ZEPPELIN-1387] Support table syntax in markdown interpreter

### What is this PR for?

Support table markdown syntax issued by [ZEPPELIN-1387](https://issues.apache.org/jira/browse/ZEPPELIN-1387?jql=project%20%3D%20ZEPPELIN)

### What type of PR is it?
[Bug Fix | Improvement]

This PR can be categorized as bug fix and improvement since it not only resolves the above issue but also support other markdown syntaxes.

### Todos
* [ ] - Check the license issue of the [pegdown](https://github.com/sirthias/pegdown) library introduced by this PR

### What is the Jira issue?

[ZEPPELIN-1387](https://issues.apache.org/jira/browse/ZEPPELIN-1387?jql=project%20%3D%20ZEPPELIN)

### How should this be tested?

Write markdown texts and compare them with expected html DOMs. I'v also included some tests for this PR.

### Screenshots (if appropriate)

### Questions:

* Does the licenses files need update?
* Does coding style is appropriate?

### Additional Comments

We might solve this issue by implementing custom table plugin for markdown4j by referring [the existing work of txtmark](https://github.com/zhenchuan/txtmark/commit/178486805e78e3d572b071ca8b9f8887a066edef).
But I think it is not good idea in regard to coverage, maintainability and efficiency since markdown4j is currently not developed actively and it costs to implement all markdown plugins which is not supported by markdown4j.

 ## Overview
 [Markdown](http://daringfireball.net/projects/markdown/) is a plain text formatting syntax designed so that it can be converted to HTML.
-Apache Zeppelin uses markdown4j. For more examples and extension support, please checkout [here](https://code.google.com/p/markdown4j/).  
+Apache Zeppelin uses [markdown4j](https://github.com/jdcasey/markdown4j) and [pegdown](https://github.com/sirthias/pegdown) as markdown parsers.
+
 In Zeppelin notebook, you can use ` %md ` in the beginning of a paragraph to invoke the Markdown interpreter and generate static html from Markdown plain text.
 
-In Zeppelin, Markdown interpreter is enabled by default.
+In Zeppelin, Markdown interpreter is enabled by default and uses the [markdown4j](https://github.com/jdcasey/markdown4j) parser.
