SAM Template for C++ S3 Lambda Example

[daniel-fudge]

After much searching I can't find an example of a C++ lambda function deployed with SAM.

I think the addition of a SAM example would be very useful for user starting to develop C++ Lambda functions.

The Rust runtime Readme has an excellent SAM example. The SAM addition to this repo would be extremely helpful.

The littermap-aws-backend project has a lambda written in C++ that deploys with SAM.
