[ZEPPELIN-4686] Update commons-lang to commons-lang3
### What is this PR for?
I noticed that the Zeppelin project mixes "commons-lang" and
"commons-lang3". I have (hopefully) changed all imports to `commons-lang3`
I use `commons-lang3` 3.7, because this version was used in several
submodules.
### What type of PR is it?
Improvement
### Todos
* [ ] - Is the replacement of `getFullStackTrace` to `getStackTrace` right?
* [ ] - commons-lang isn't deleted from main `pom.xml`. Okay?
### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-4686
### How should this be tested?
* Unit-Tests withTravis CI
https://travis-ci.org/github/Reamer/zeppelin/builds/663565663
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
Author: Philipp Dallig <philipp.dal...@gmail.com>
Closes #3691 from Reamer/commons-lang3 and squashes the following commits:
