Gregory Thiemonge 6fe5df6fd8 Fix controller worker graceful shutdown ... 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.
