[YARN] [SPARK-20756] yarn-shuffle jar references unshaded guava
and contains scala classes
## What changes were proposed in this pull request?
This change ensures that all references to guava from within the yarn
shuffle jar pointed to the shaded guava class already provided in the jar.
Also, it explicitly excludes scala classes from being added to the jar.
## How was this patch tested?
Ran unit tests on the module and they passed. I am in the process of taking
this jar and deploying it on a yarn cluster, and making sure the YARN node
managers come up and that the shuffle via shuffle service works.
