This change set provides a significant update to the nova-powervm drivers dev-ref. Rebases the documentation to reflect the development that has been done over the last several months. Updates the readme to reflect the execution that has completed. Removes the fake_driver that is not useful. Change-Id: I1910db886df89f884f3c399d6aab1eebdf10b5e0
