Add unit tests for main Armada handler
This PS adds unit tests for the armada handler in armada.handlers.armada. These unit tests are among the most important as the Armada handler itself interacts with most every other part of the application. Note that the current unit tests are not only incorrect (they don't pass) but they skip unconditionally as well. So this PS is needed to correctly implement the intent behind the original unit tests herein. Change-Id: Iecb3e540e1d52eb5a25d9f6825b3d0f5339ede2a
