Provide a hook to call OpenTelemetry.SuppressInstrumentationScope.Begin

[nblumhardt]

Usage:

Log.Logger = new LoggerConfiguration()
    .WriteTo.OpenTelemetry(options =>
    {
        options.OnBeginSuppressInstrumentation =
            OpenTelemetry.SuppressInstrumentationScope.Begin;
        // ...

Fixes #41

Thanks for turning this around so quickly Nick. I can confirm it's fixed the issue for me! One thing though - the signature of the Begin() method is:

 IDisposable OpenTelemetry.SuppressInstrumentationScope.Begin(bool value = true);

Due to the optional parameter it doesn't match the type Func<IDisposable> expected by the new OnBeginSuppressInstrumentation property, so I was getting compiler errors using your example implementation. I had to instead use the following:

Log.Logger = new LoggerConfiguration()
    .WriteTo.OpenTelemetry(options =>
    {
        options.OnBeginSuppressInstrumentation =
           () => OpenTelemetry.SuppressInstrumentationScope.Begin();
        // ...

Thanks for checking this out @badgeratu 🙇

I think, since OpenTelemetry suppression will be the vast majority of use cases for this API now and in the future, I might just change the expected signature to match. I'll push an update :-)
