Cancel a running training job associated with the given
predictive_query_id. Cancellation is an asynchronous "best effort"
operation. Users can call GET
"predictive_queries/{predictive_query_id}/training_status" to verify if
the training job has been successfully cancelled. No action will be
taken in the following cases:
- No training job is actively running.
- The job has already been completely, regardless of whether the training succeeded or failed.
