Add metadata to aws/invoke return values

[jeroenvandijk]

Probably this needs to be solved in a similar way to #10 and #11

From https://github.com/cognitect-labs/aws-api#explore

(aws/invoke s3 {:op :ListBuckets})
;; http-request and http-response are in the metadata
(meta *1)

[borkdude]

What does this metadata look like in practice? Is it pure data?

[jeroenvandijk]

It also contains the input stream:

(clojure.pprint/pprint (meta (aws/invoke s3 {:op :DeleteBucket :request {:Bucket "babashka-test2"}})))
{:http-request
 {:request-method :delete,
  :scheme :https,
  :server-port 443,
  :uri "/babashka-test2",
  :headers
  {"x-amz-date" "20210105T115030Z",

Maybe we can leave this out for now. It would surprise me if you could do anything with that inputstream, since it was already read by aws-api itself probably.

I think the request metadata can be returned in a :pod.babashka.aws/meta key (without the response inputstream) so we can add that to the response on the client side
