METRON-1185: Stellar REPL does not work on a kerberized cluster when calling functions interacting with HBase
## Contributor Comments
Because we put all the jars on the classpath from `$METRON_HOME/lib` via a glob, if we get the wrong order, we get classpath issues around Stopwatch (i.e. more recent guava may sneak onto the classpath first). This is non-deterministic and can cause issues randomly. Instead of a glob, we should choose one of the uber jars with all the metron Stellar functions baked in and allow users to provide any extra directories we should include via an env variable. Also, we are not pulling the full hbase classpath, so in a kerberized cluster we do not get all of the configs on the classpath, so we can't find always find tgts.
