[ZEPPELIN-3551] Upgrade Scala to 2.11.12
### What is this PR for?
This is just to update scala to 2.11.12 which to be consistent with spark
(SPARK-24418).
This PR takes over and closes #3033
There was a minor conflict which my PR
(https://github.com/apache/zeppelin/pull/3206) introduced. That change is
compatible with both Scala 2.11.8 and 2.11.12 so we don't need to change it
anymore.
