Hadoop query service jar is created during packaging

Since we had to check in the jar every time we made the smallest change, it was adding
20 megs to the repo each time, which builds up.

Now, 'chorushdfs' is added as a submodule so we can build the jar as needed

Also removed some code that was deleting the ".bundle" directory after running
any task that started with "packaging" -- we delete this directory early on while
packaging.sh is running, which should be enough.
