ZEPPELIN-1977. spark 2.1 uses a more recent commons-lang3 ### What is this PR for? The issue is that spark 2.1 use `commons-lang3` 3.5 while `zeppelin-interpreter` use 3.4. We can not just upgrade `commons-lang3` to 3.5, as it just make spark 2.1 work, but would fail other versions of spark. This PR remove `commons-lang3` from zeppelin-interpreter. We should keep zeppelin-interpreter's dependencies as minimum as possible. We can remove other dependencies (like `commons-lang`) from `zeppelin-interpreter` in a followup PR. ### What type of PR is it? [Bug Fix] ### Todos * [ ] - Task ### What is the Jira issue? * https://issues.apache.org/jira/browse/ZEPPELIN-1977 ### How should this be tested?
