Implement pipeline instrumentation metrics

[jade-guiton-dd]

The "Pipeline Component Telemetry" RFC defines generic metrics and logs to monitor the data passing through the interface between pipeline components, as well as a mechanism for capturing this telemetry. It now needs to be implemented, probably as a wrapper around the Consumer interface inserted at the pipeline graph level.

This new telemetry should include the component-identifying attributes defined in the same RFC. Instead of rederiving these attributes, it should make use of the implementation of #12217.

If I'm not mistaken there isn't already an issue tracking this right?

I don't think this can be considered completed until the "outcome = refused" case has been implemented. (To be clear: I do think it makes sense to put that in a separate PR since the implementation may be a bit subtle.)
