What does this PR do?
This PR currently hides all the OTel specific things in the sampling code behind traits, so the sampling logic can be moved to a separate crate.
Motivation
Make the sampling code more generic and move it into a separate crate so it can be reused.
Additional Notes
The benchmarks are on par with the original code. Some improvements and a few minor regressions. There will be additional changes that move the code out.
