Adds tasks, schedules, and preconditions to the specified pipeline. You can use PutPipelineDefinition to populate a new pipeline.
PutPipelineDefinition also validates the configuration as it adds it to
the pipeline. Changes to the pipeline are saved unless one of the following three validation errors exists in the pipeline.
An object is missing a name or identifier field. A string or reference
field is empty. The number of objects in the pipeline exceeds the maximum allowed objects. The pipeline is in a FINISHED state. Pipeline object definitions are passed to the PutPipelineDefinition action and returned by the GetPipelineDefinition action.
