Pipeline Shutdown Reporter

With the work for #7291, I suspect that we will have to rewrite the current implementation of the `PipelineShutdownReporter`, since most of the internal will change.

Work needed TBD,

Read issue #7291 and inspect the current PipelineShutdownReporter implementation to understand which internals are changing. The issue does not define the required rewrite or a completion criterion, so the expected result remains to be clarified before implementation can begin.
