Start a pipeline run. Field parameters can be used to provide variable settings for a custom pipeline run. Use the wait parameter to wait for the pipeline to be COMPLETED (or other state provided by the state parameter) before the action completes. When waiting for a COMPLETED pipeline, the action will fail if the pipeline result is not successful unless the continue parameter is specified. Alternatively, the same wait related parameters can a used on a separate getPipeline action enabling multiple pipelines to be started in a script without wait and then followed later by getPipeline with wait to handle results.
