[ZEPPELIN-2724] Another Attempt to solve the dead lock problem
### What is this PR for?
https://github.com/apache/zeppelin/pull/2465
This is my attempt under the help with my colleague. We originally wrote
the patch in Java 8 based on Zeppelin 0.6.0. Today, I rewrite this part in Java
7 based on Zeppelin master. I confirm the code I wrote for Zeppelin 0.6.0
solved the dead lock problem. We have over 80 websocket connections for several
months and our Zeppelin 0.6.0 works well and didn't crash for websocket reason
since we apply the patch.
I will explain the patch in detail if necessary.
### What type of PR is it?
[ Improvement ]
### Todos
* [ ] - To be verified
### How should this be tested?
Our QA wrote a python script, I will post it here later.
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
