-- Stops a running task.
--
-- 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' and a 30-second timeout, after which 'SIGKILL' is sent and the
-- containers are forcibly stopped. If the container handles the 'SIGTERM'
-- gracefully and exits within 30 seconds from receiving it, no 'SIGKILL'
-- is sent.
