AWS lambda support

For instrumenting AWS Lambda, it seems like it'd be ideal to use [Lambda Extensions](https://aws.amazon.com/pt/blogs/aws/getting-started-with-using-your-favorite-operational-tools-on-aws-lambda-extensions-are-now-generally-available/) to deliver error reports. At first glance it looks like the `async` option would be the way to integrate with Lambda Extensions. Do any of the Sentry libraries for other languages hook into Lambda Extensions? Would there be another way to do that with the Sentry Ruby SDK?
