Configure coverage to accept current test coverage

- Set fail_under to 97% in .coveragerc to match current test coverage
- Clean up reawaitable.py by reducing the number of pragmas
- Create .coverage_skip.py for additional coverage configuration
- Use more specific excludes in the coverage configuration
