### What is this PR for?

display system using MathJax library.

### What type of PR is it?
Feature
### Todos
* [x] - Format math formula with MathJax library
### What is the Jira issue?
https://issues.apache.org/jira/browse/ZEPPELIN-777
### How should this be tested?
try run following codes.
```
%md
When \\(a \\ne 0\\), there are two solutions to \\(ax^2 + bx + c = 0\\) and
they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
```
Note MathJax works better with `markdown.parser.type` property set
`pegdown`, in markdown interpreter. With default markdown4j parser, some
formula is not well displayed. (for example, ax^2) I think this will not be a
big problem because of we'll remove markdown4j
https://github.com/apache/zeppelin/pull/1594
```
%sh echo -e "%html \$\$a = b\$\$"
```
```
%spark println("%html $$b = c$$")
```
