[DRAFT] Common http telemetry builder interface

[trask]

Built on top of #12858 for now...

I'm not sure if we want/need this, but it is part of what motivated #12858

@zeitlinger do you remember if this has any concrete benefits in our codebase (other than enforcing consistency, which could be a good enough reason)?

If you want to look at it, here's the commit to look at: 0bab846

• consistency
• maybe get rid of the delegation in the telemetry builders (e.g. use inheritance instead) - not sure if this still makes sense after the latest changes
