Pull Request Overview

This PR updates internal semantic convention classes in the Azure Monitor OpenTelemetry autoconfigure module to use v1.37.0 of the OpenTelemetry semantic conventions. The purpose is to maintain consistency with the latest OpenTelemetry standards while keeping the internal implementation isolated from external dependencies.

Key Changes

• Replaces usage of a single monolithic SemanticAttributes class with specific semantic convention classes organized by domain (HTTP, DB, URL, etc.)
• Adds new semantic convention classes for both stable and incubating attributes from OpenTelemetry v1.37.0
• Updates imports and references throughout the codebase to use the new attribute classes
