AWS Lambda initial POC

[BelSasha]

What is supported?

1. Create and execute a lambda (one or multiple .py files), including installing python libraries.
2. Function call methods: map, starmap, save, share, from_name, for_config
3. A factory method, which creates AWSLambdaFunction instance, and sends it to AWS.
4. Document (rst file) was created.

Tests which were executed and passed:

1. AWS Lambda Function tests (all testing suite)
2. Function tests (minimal level)
3. Module tests (minimal level)

Overall this is amazing work and a solid PoC. Next I think we should discuss the API surface and how to make it smoother with the core Function API, the access details, and some of the packaging mechanics.
