Provide an extension for AWS Lambda Detector

[azhar-hosenbocus-cko]

Component

OpenTelemetry.Resources.AWS

Is your feature request related to a problem?

OpenTelemetry.Resources.AWSResourceBuilderExtensions does not expose AWS Lambda Detector.

The required implementation is available at OpenTelemetry.Instrumentation.AWSLambda.Implementation.AWSLambdaResourceDetector under an internal class.

What is the expected behavior?

OpenTelemetry.Resources.AWSResourceBuilderExtensions can expose an AWS Lambda Detector to allow enriching resource builders with AWS Lambda metadata.

Which alternative solutions or features have you considered?

I can implement my own extension to do that but I believe having this in this library would also benefit the community.

Was there any reason the Lambda Detector was not implemented similar to the other detectors extensions (ECS, EKS...)?

Happy to raise a PR for this.

Use the AWSLambda-specific package in your application if you use Lambda functions.

I see its only exposed for the TracerProviderBuilder, but not for LoggerProviderBuilder?

I would like to have my logs enriched with these:

opentelemetry-dotnet-contrib/src/OpenTelemetry.Instrumentation.AWSLambda/Implementation/AWSLambdaResourceDetector.cs

Lines 27 to 32 in a5f3fc0

	.AddAttributeCloudProviderIsAWS()
	.AddAttributeCloudRegion(AWSLambdaUtils.GetAWSRegion())
	.AddAttributeFaasName(AWSLambdaUtils.GetFunctionName())
	.AddAttributeFaasVersion(AWSLambdaUtils.GetFunctionVersion())
	.AddAttributeFaasInstance(AWSLambdaUtils.GetFunctionInstance())
	.AddAttributeFaasMaxMemory(AWSLambdaUtils.GetFunctionMemorySize())

Ah I see. In that case it sounds like we should extend the implementation in the AWSLambda package to enable that.
