post https://api.scale.com/v1/task//cancel
This endpoint cancels a task so that it will not be completed.
You may only cancel pending tasks, and the endpoint will return a 400 error code if you attempt to cancel a completed task
If the task to be cancled had a unique id, specifying clear_unique_id=true will remove the unique id. Canceling tasks is idempotent such that calling this endpoint multiple times will still return a 200 success response.
