The downstream libraries' clirr check are failing due to protobuf rc release. For example, [java-bigtable](googleapis/java-bigtable#2737). Skipping clirr check in sdk-platform-java-config so we don't have to skip it for each downstream library. We should re-enable them after protobuf upgrade is completed.

Summary of Changes

Hello @diegomarquezp, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request is a proof-of-concept for integrating OpenTelemetry tracing into the GAX Java library. It establishes a new, abstract tracing layer and provides a concrete OpenTelemetry implementation. The changes also enable the automatic inclusion of client artifact names in the tracing context, which will allow for more granular and client-specific observability data. This work aims to enhance the monitoring and debugging capabilities of generated GAPIC clients.

Highlights

OpenTelemetry Integration: Introduced new classes (OpenTelemetryTracingRecorder, OpenTelemetryTracingTracer, OpenTelemetryTracingTracerFactory) to provide OpenTelemetry-based tracing capabilities within the gax-java library.
Tracing Abstraction: A new TracingRecorder interface was added to abstract the underlying tracing recording mechanism, allowing for flexible integration with different observability frameworks.
Artifact Name Propagation: Enhanced GapicContext and StubSettings to support an artifactName property. This name is now propagated to the ApiTracerFactory in ClientContext, enabling client-specific metadata in generated traces.
Build System Updates: The rules_java_gapic/java_gapic.bzl build rule was updated to accept and pass the artifact_name argument during GAPIC code generation.
New Integration Test: An integration test (ITOtelTracing.java) was added to the java-showcase module to verify the functionality of the new OpenTelemetry tracing implementation.

Code Review

This pull request introduces OpenTelemetry tracing capabilities and the ability to specify an artifact name for generated GAPIC clients. It involves adding new interfaces and implementations for tracing, updating the GapicContext and StubSettings to support artifact names, and integrating these changes into the code generation process and client context creation. The changes also include updating build configurations and golden files to reflect the new functionality. Overall, the changes are well-structured and introduce significant new features for observability and client identification.
