Allow to set variables via datadog.yaml

[xrn]

Expected Behavior

Would be cool if I can use

• DD_TRACE_ENABLED
• DD_TRACE_STARTUP_LOGS
• DD_VERSION
• DD_UNIVERSAL_INSTRUMENTATION

via datadog.yaml config for my lambdas - now I have 90% of DD configuration there but these if I am correct are not supported.

For me as a user is not clear and correct why DD_ENV could be move to yaml as env and is working but DD_VERSION can not be used as version there. Also second example DD_CAPTURE_LAMBDA_PAYLOAD works as capture_lambda_payload but DD_UNIVERSAL_INSTRUMENTATION does not

Also variable site - this is not clear for me:

1. datadog-lambda-go has in config option to set site - but I can define it via datadog.yaml if I am using extension. Am I correct that if I have extension then does not matter what I will define in datadog-lambda-go site parameter? Or how it works?

Specifications

• Datadog Go Lambda package version: 1.18.0
• Extension v35
• Go version: 1.18

Following #116 (comment) I understand that DD_UNIVERSAL_INSTRUMENTATION will be not supported - but what about others?

Closing the issue for now since we moved the convo to the community slack and resolved.
