@xrmx , I would propose we merge this one before the common library is ready. It will provide testing needed to switch to the new library.

Also, please review the PRs which are pre-requirement to switching to the util library. https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3862 https://github.com/open-telemetry/opentelemetry-python-contrib/pull/3891
