Hello Team,
Opening this request on behalf of customer for pipelines in pipelines as https://github.com/tektoncd/experimental/tree/main/pipelines-in-pipelines Do update the ETA if it's already in process within OpenShift Pipelines.

Please find more info below that will help to understand the exact requirements.

1. What is the nature and description of the request?[What is impacting without this feature?, How it will be helpful to you]

ANS: Currently, customer have a large number of pipelines that are unable to reuse common parts of those pipelines causing resource issues with the OpenShift cluster due to the number of pipelines that kick off. With this feature customer be able to reuse pipelines in pipelines and prevent our clusters from being impacted by the resource requirements having to spin up additional worker nodes in AWS. From a technical perspective, when additional worker nodes are added cluster operators get moved around causing temporary outages and through this feature, CU feel will prevent or minimize the current impact CU experiencing.

2. Why does the customer need this? (List the business requirements/urgency of RFE here)

ANS: CU need this feature as additional worker nodes incur a financial cost and also disrupt our existing cluster level operators by being rescheduled. This is critical and would like a timeline so CU can plan ahead accordingly.
