Add environmentId and externalVolumeMountIds

            self.app_unpublish()
        app_id = self._app_id
        if app_id is None:
            # No App Exists creating one
            app_id = self.__app_create(hardware_tier_id=hardwareTierId)
        url = self._routes.app_start(app_id)
        request = {
            "hardwareTierId": hardwareTierId,
             "environmentId": environmentId,
             "externalVolumeMountIds": externalVolumeMountIds
        }
        response = self.request_manager.post(url, json=request)
        return response
