Restructure Rackspace resources

During doc generation, resources have their own templates and need
to be separate from non-resource modules.  This removes the ``heat``
``engine`` and ``plugins`` folders and moves all resources into a
``resources`` folder, effectively separating the custom Rackspace
Client from custom Rackspace resources.
