Fix an issue that prevents graceful shutdown of controller workers. cotyledon.Service.terminate function is by definition the graceful termination function and doesn't have any 'graceful' optional boolean argument (https://cotyledon.readthedocs.io/en/latest/api.html). Because of this error, message_listener.wait() was never called in the consumers' termination functions, so flows could be interrupted before completion and could leave resources such as load balancer in a PENDING_* provisioning state. By default cotyledon.Service terminates the server after a timeout if the worker could not shutdown itself gracefully. The default value for the timeout is 300 seconds (set in devstack plugin) and can be overriden using the graceful_shutdown_timeout setting in octavia.conf The default value will be updated to a lower value when work on persistant taskflow will be merged.
