* Rename otel/label -> otel/attr Leave the imported name alone, to avoid a large diff and conflicts * Better import comment * Update CHANGELOG.md Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com> * otel/attr -> otel/attribute * Missed the changelog entry * Get rid of import renaming * Merge remaining conflicts Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com> Co-authored-by: Anthony Mirabella <a9@aneurysm9.com>
