Feature request: HTTP2 support

Node.js supports HTTP2, and it appears the Lambda endpoints now too support HTTP2 (see below).

It would be considerably more efficient if it were possible to invoke Lambda functions using HTTP2 to avoid needless TLS handshakes and high concurrent of TCP/IP connections for HTTP/1.1 support.

Is there any plan to add HTTP2 support to this library any time soon?

Thanks for submitting this request.

This is a feature that we’re considering for the next major version of the SDK.
