Now that #11406 is merged, this should be ready for another review. Important note - this doesn't actually change anything meaningful for users yet. It's just a way of managing the nodes in the graph internally that is closer to what the RFC states should be presented to users. Further work will be needed before users see any standardization of attributes.

I've converted this back to a draft until a decision is made on https://github.com/open-telemetry/opentelemetry-collector/issues/11814. I believe the attribute sets used in this PR suffer from the same problem described in the loggers and that we should solve that problem before this change is meaningful.
