Zero-code Telemetry 2: Implement package

[davorrunje]

Once we implement and register the package, we can use telemetry automatically with no code change to the project:

pip install ag2, opentelemetry-distro
opentelemetry-bootstrap -a install

opentelemetry-instrument --traces_exporter console --metrics_exporter none python workflow.py

See [Python zero-code instrumentation] (https://opentelemetry.io/docs/zero-code/python/) for details

Examples:

• Package for LangChain
• Registration of the package
