Provide ScopeName constant for logging bridges

[galecore]

Problem Statement

Most of the integrations in contrib automatically provide some ScopeName when working with top-level telemetry providers. Example search for ScopeName const yields lots of examples - https://github.com/search?q=repo%3Aopen-telemetry%2Fopentelemetry-go-contrib%20ScopeName&type=code

At the same time, logging bridges don't have these scope names, leaving the user in charge of setting the package for LoggerProvider.Logger(...). Why is there no ScopeName defined for logging bridges? Is it expected that callers hardcode and pass repo module names when setting up logging bridges?

Proposed Solution

Add const ScopeName = "..." for every logging bridge package - otelslog, etc.

Alternatives

Hint on the expected value for LoggerProvider.Logger(...) when using log bridges in examples and/or documentation.

Prior Art

Example search for ScopeName const yields lots of examples - https://github.com/search?q=repo%3Aopen-telemetry%2Fopentelemetry-go-contrib%20ScopeName&type=code

It's not rare to see TracerProvider.Tracer(ScopeName) or MeterProvider.Meter(ScopeName)calls in contrib.

The logging bridge is not meant to provide the scope name. It is a bridge, not instrumentation.

The instrumentation that uses the logging library backed by a bridge needs to provide an appropriate scope name.

Could you maybe clarify what the appropriate scope name would be for a global slog logger that uses otelslog as bridge? @MrAlias

The provided name needs to uniquely identify the code being logged. This is most commonly the package name of the code.

The specifics are going to depend on what your code-base is named and how it is structured.
