Instantiates a template and begins execution.
This method is equivalent to executing the sequence xref_CreateWorkflowTemplate, xref_InstantiateWorkflowTemplate, xref_DeleteWorkflowTemplate.
The returned Operation can be used to track execution of
workflow by polling
operations.get][google.longrunning.Operations.GetOperation]
.
The Operation will complete when entire workflow is finished.
The running workflow can be aborted via
operations.cancel][google.longrunning.Operations.CancelOperation]
.
This will cause any inflight jobs to be cancelled and
workflow-owned clusters to be deleted.
The Operation.metadata][google.longrunning.Operation.metadata]
will be
