Exclude org.apache.hadoop classes from tables-test-fixtures uber jar (#140)

## Summary

<!--- HINT: Replace #nnn with corresponding Issue number, if you are
fixing an existing issue -->

tables test fixtures fat jar ships with a version of OSS hadoop thats
incompatible with newer version of li-hadoop (specifically 2.10.0.780).
When li-openhouse was upgraded to this version of li-hadoop, unit tests
depending on tables test fixtures fat jar started to fail when starting
a test hdfs cluster.
