RESTful Lambda should expose the execution context

[sorin-costea]

I can develop fine RESTful APIs with Quarkus, but nobody seems to know a way to access the Lambda context from within the JAX-RS handlers. I asked both in Zulip and StackOverflow, no answers.

I assume there should be a way to inject it, because for example it's very useful to log the Lambda execution ID to trace call flows, and without the context there's no way to know it. I assume it's the amazon-lambda-http who needs this extension...

I noticed there's also some OpenTracing support, but that only wraps calls without giving access from code (and I don't think works with CloudWatch anyway)
