Feature request: check for Lambda runtimes close to their deprecation dates

[rdegraaf]

Is your feature request related to a problem? Please describe.

Each AWS Lambda function is configured to use a specific runtime environment. AWS occasionally deprecates these runtime environments as old programming language releases go out of support. See https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html for information on currently-supported runtimes and scheduled deprecations.

Describe the solution you'd like

ScoutSuite should flag every Lambda Function whose runtime is scheduled to be deprecated within the next year.
