add support for running quarkified amazon lambdas on AWS infrastructure

Just what it says on the tin.

Ultimately, I'd like to replace that bootstrap script with an actual native binary but we'll need quarkus to support command line apps first.

I wonder if we really need command line app support to make this work fully within a single process. Perhaps there's some combination of reactive REST client, plus CDI startup listener or application scope bean, which would allow an initial request to be fired with a completion stage that takes the response, feeds it through the REST machinery to the REST handler, takes the response from that, and feeds it back to Lambda as a response request.

I tried the CDI listener approach for a while and had issues with it. However, having figured out all the other bits, i'm happy to take another swing at it. But in another PR. ;)

This will do for a start.
