    tests: refactors and cleans up test_rbd.py

    In the unit tests' setUp, it was setting self.mock_rbd = mock_rbd
    (where mock_rbd is the argument passed by @mock.patch.object) and
    setting all sorts of properties onto self.mock_rbd, but mock_rbd
    would become invalid after setUp finished, as the mock.patch
    decorator would remove the patched mock. The same applies with
    mock_rados.

    This patch addresses this issue by refactoring and simplifying the
    unit tests.
