initial implementation of lambda

[nabuskey]

What does this PR do?

Adds an implementation of Lambda. The implementation creates a Lambda function from a container image with a basic role. More policies can be attached to this role using nested compositions.

NOTE: The container composition consists of two resources from different providers because IAM role creation does not work in terrajet provider ATM: https://github.com/crossplane-contrib/provider-jet-aws/issues/176

Motivation

Trying to complete AWS serverless resources
