Add hive test files to repository. Remove download script.

This PR removes our test dependence on files hosted at Berkeley by checking the test queries and answers into the repository.  This should also fix the maven Jenkins build.

I realize this is a *giant* commit.  But size wise its actually pretty small.  We are only looking at ~1.2Mb compressed (~30Mb uncompressed).  Given that we already have a ~80Mb file permanently added to the spark code lineage, I do not think that this will change the developer experience significantly.

Furthermore, I think it is good engineering practice to consider such test support files as "code", since changes to them would indicate a change in functionality.  These files were only excluded from the initial PR as I wanted the diff to be readable.
