server's action confirm_resize return wrong status code v3

[Alex Xu]

server's action confirm_resize return 204 now, but it should be 202

    @wsgi.response(202)
    @wsgi.serializers(xml=FullServerTemplate)
    @wsgi.deserializers(xml=ActionDeserializer)
    @wsgi.action('confirm_resize')
    def _action_confirm_resize(self, req, id, body):
        context = req.environ['nova.context']
        instance = self._get_server(context, req, id)
        try:
            self.compute_api.confirm_resize(context, instance)
        except exception.MigrationNotFound:
            msg = _("Instance has not been resized.")
            raise exc.HTTPBadRequest(explanation=msg)
        except exception.InstanceInvalidState as state_error:
            common.raise_http_conflict_for_instance_invalid_state(state_error,
                    'confirm_resize')
        return exc.HTTPNoContent()

The 'return exc.HTTPNoContent()' overwrite the '@wsgi.response(202)'

    Fix status code of server's action confirm_resize for v3

    The status code of confirm_resize should be 202, but it
    returns 204 now. That because it returns HTTPNoContent
    that overwrites the status code of decorator 'wsgi.response(202)'

    And adds API samples for confirm_resize that used to test
    the status code of confirm_resize.

    Partially implements blueprint v3-api-unittests
    Closes-bug: #1233561
