[WIP] ZEPPELIN-335. Pig Interpreter
### What is this PR for?
Based on #338 , I refactor most of pig interpreter. As I don't think the
approach in #338 is the best approach. In #338, we use script `bin/pig` to
launch pig script, it is different to control that job (hard to kill and get
progress and stats info). In this PR, I use pig api to launch pig script.
Besides that I implement another interpreter type `%pig.query` to leverage the
display system of zeppelin. For the details you can check `pig.md`
### What type of PR is it?
[Feature]
### Todos
* Syntax Highlight
* new interpreter type `%pig.udf`, so that user can write pig udf in
zeppelin directly and don't need to build udf jar manually.
### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-335
### How should this be tested?
Unit test is added and also manual test is done
### Screenshots (if appropriate)
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
