Split logging functionality into API and SDK like other signals

[tigrannajaryan]

The Log specification recently went through a series of modifications, the result of which is that now we have Log API and Log SDK specification, similar to the separation we have for traces and metrics.

Please refactor the Python's experimental implementation to match the specification, if it is not already.

@lzchen I believe we already completed this except for the proxies, which is a Python SDK thing to work around specific early access issues. Is there anything pending I missed?

This is great.

I checked the example and I think it is using LoggerProvider from the SDK. Perhaps it can be updated to show obtaining the global LoggerProvider from the API, similar to how it obtains the global TracerProvider?

[srikanthccv]

Sure, we'll update that.

I am closing this issue since splitting into API and SDK is done. Thanks.
