feat(sdk): add OpenTelemetry logging support

[jinsongo]

• I have added tests that cover my changes.
• If adding a new instrumentation or changing an existing one, I've added screenshots from some observability platform showing the change.
• PR name follows conventional commits format: feat(instrumentation): ... or fix(instrumentation): ....
• (If applicable) I have updated the documentation accordingly.

I set the default value to false for is_logging_enable() because the OpenTelemetry logging SDK is currently experimental.
The following is the console output from my test with logging enabled.

@nirga could you review the feature to comment if it is what we need for traceloop logging? Thanks. cc @gyliu513

[nirga]

Thanks @jinsongo
Yes it's a good start, we can then use it in the instrumentations to log prompts instead of the span attributes.
