Too many local prerequisites to build/deploy

[athewsey]

Lambda packaging is nicely containerized via Docker and SAM so only these need to be installed on the host machine... But rolling in the front end code has introduced prerequisites of NodeJS and even a node-gyp compatible version of Python, which are higher bars to meet.

Would be great to reduce the local machine prerequisites for running the deploy script if possible.

pre-packaged Node and Python dependency into lambda layer and we can skip the sam built phase for the backend lamda function. For the front-end, can pre-built react to into html css and js.
