FR: adding OpenTelemetry instrumentation package

[SiriusKoan]

Problem

Tracing is critical to modern monitoring, and many popular packages build their own OpenTelemetry instrumentation to provide tracing.
However, there seems no similar solution for line-bot-sdk-python now, and developers have to do manual instrumentation or use existing instrumentation from other related packages, such as opentelemetry-instrumentation-flask (if website hosted with Flask) and opentelemetry-instrumentation-requests (if making HTTP requests manually).

Solution

Allowing tracing the Line API made from this SDK by simply installing a package named opentelemetry-instrumentation-<a good name for line-bot-sdk-python>.

Thank you for using the SDK, and thank you for the proposal in this issue.

We agree that tracing is important for modern observability. However, calls made by line-bot-sdk-python are essentially performed via standard HTTP clients. In most cases, using existing OpenTelemetry instrumentations such as opentelemetry-instrumentation-requests or opentelemetry-instrumentation-urllib3 already allows tracing of API calls made through this SDK.

Providing an official, SDK-specific OpenTelemetry instrumentation would require ongoing maintenance effort, including tracking OpenTelemetry API/SDK compatibility, defining semantic conventions, and maintaining tests. For this reason, we’re sorry to say that we do not currently have plans to provide a dedicated instrumentation package.

Thank you for your understanding.
