[feature request] source generator using semantic conventions

[thompson-tomo]

Component

None

Is your feature request related to a problem?

I want to eliminate the need to define a collection of strings representing my attribute keys.

What is the expected behavior?

I define a struct/class in my project like below

[attributes("disk")]
internal static partial struct DiskAttributeNames
{
}

Once generator runs you end with

internal static partial struct DiskAttributeNames
{
  internal static partial struct disk
  {
    internal static partial struct io
    {
      internal const string direction = "disk.io.direction";
    }
  }
}

And you can use them via DiskAttributeNames.disk.io.direction

Which alternative solutions or features have you considered?

Use nuget package of all semconv attributes but adds a transitive dependency to customer apps which can cause breaking changes

@thompson-tomo, I like the idea. Do you have some working PoC? Would you like to contribute?

[thompson-tomo]

@Kielek i don't currently have a POC but I am potentially interested in working on it to gain exposure to writing a source generator.

What I was thinking about was introducing a OpenTelemetry.SemanticConventions.Abstractions package which contains the generator & the attribute.
