-- Stops a running task. Any tags associated with the task will be deleted.
--
-- When StopTask is called on a task, the equivalent of @docker stop@ is
-- issued to the containers running in the task. This results in a
-- @SIGTERM@ value and a default 30-second timeout, after which the
-- @SIGKILL@ value is sent and the containers are forcibly stopped. If the
-- container handles the @SIGTERM@ value gracefully and exits within 30
-- seconds from receiving it, no @SIGKILL@ value is sent.
--
-- The default 30-second timeout can be configured on the Amazon ECS
-- container agent with the @ECS_CONTAINER_STOP_TIMEOUT@ variable. For more
-- information, see
-- <https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-agent-config.html Amazon ECS Container Agent Configuration>
-- in the /Amazon Elastic Container Service Developer Guide/.
