HW QE Changes

1. Changed oozie version to 3.2.2 and used oozie.version instead of falcon.oozie.version to get the tests to compile. We can switch to falcon.oozie.version when this code is merged into apache as then the user can build it in the same git repo.

2. Made most of the changes that we have made till now. Few that are left are changing ArrayList to List and i could not do that as patches were not applying. They are simple changes which can be done later as well.
