The current REST API tests have a lot of rooms to be improved like:
- mocking the whole module of the API wrapper
- Use test_data.cinder_data
- Use response.json attribute to decode responses as much as possible
APIResourceWrapper.to_dict() method of openstack_dashboard.api.base
is changed to refer attributes of an object itself instead of
self._apiresource. There is a case where APIResourceWrapper class
defines its own attributes and such attributes should be used in
to_dict() method. If self._apiresouce is referred these attributes
are not considered. We need to consume attributes of a class object
itself. It helps us write unit tests using sample test data.
