Topic to Evaluate

How to unblock #387230 (closed), #15603 (closed)

We suspect that dealing with cancelled pipelines will be more straight forward than timed out pipelines, so we would like to focus initial efforts on that aspect of the issue.

• Review the POC efforts to resolve #15603 (closed)
• Confirm if there is a blocker in the runner project by working with the Runner team member to figure out what needs to happen on the Rails side to unblock the runner change.
• Document the additional changes that need done in #387230 (closed) to make after_script work for cancelled pipelines. Focus primarily on cancelled pipelines to start, if time permits then look at timed out pipelines where additional changes should be noted in #15603 (closed).
