Implement an API endpoint that gives details about all pipelines triggered from a specific pipeline schedule

Currently, we do not have any way of co-relating pipelines with the pipeline schedules they were scheduled from.

It would be nice to have an API like GET /projects/:id/pipeline_schedules/:pipeline_schedule_id/pipelines that gives the list of pipelines that were triggered via a specific pipeline schedule.

I received this request from a family member that uses GitLab at their place of work:

We have multiple pipeline schedules setup at work and we'd like to form some statistics about how many of our pipelines executed via a specific schedule actually succeeded/failed/got interuppted. However, we can't figure out a way to get information about find all pipelines triggered via a specific schedule, so that we can eventually look at all status of these pipelines and build some statistics. Is this possible to do via the API?
