-- Validates the specified pipeline and starts processing pipeline tasks.
-- If the pipeline does not pass validation, activation fails.
--
-- If you need to pause the pipeline to investigate an issue with a
-- component, such as a data source or script, call DeactivatePipeline.
--
-- To activate a finished pipeline, modify the end date for the pipeline
-- and then activate it.
