Method: projects.regions.workflowTemplates.instantiateInline

Instantiates a template and begins execution.

This method is equivalent to executing the sequence workflowTemplates.create, workflowTemplates.instantiate, workflowTemplates.delete.

The returned Operation can be used to track execution of workflow by polling operations.get. The Operation will complete when entire workflow is finished.

The running workflow can be aborted via operations.cancel. This will cause any inflight jobs to be cancelled and workflow-owned clusters to be deleted.

The Operation.metadata will be WorkflowMetadata.

On successful completion, Operation.response will be Empty.
