Response {'task': {'createdAt': 'timestamp',

'stoppedAt': 'timestamp',
'stoppedReason': 'string'}}
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.

string
An optional message specified when a task is stopped. For example, if you are using a custom scheduler, you can use this parameter to specify the reason for stopping the task here, and the message will appear in subsequent DescribeTasks API operations on this task. Up to 255 characters are allowed in this message.
