No UI changes, API only

How to set up and validate locally

1. Create a project with a .gitlab-ci.yml
2. Create a pipeline schedule
3. Trigger the schedule multiple times
4. Use https://docs.gitlab.com/api/pipeline_schedules/#get-all-pipelines-triggered-by-a-pipeline-schedule and try passing some of the new parameters. I tested with sort and expect the others to work fine as I'm re-using the existing finder
