feat(awslambda): add new check `awslambda_function_vpc_is_in_multi_azs`

puchy22 commented 3 weeks ago

Context

New check that ensures AWS Lambda functions connected to a Virtual Private Cloud (VPC) are distributed across multiple Availability Zones (AZs). This is crucial for maintaining high availability and resilience, as deploying Lambda functions in a single AZ can lead to a single point of failure, potentially disrupting operations if that AZ becomes unavailable.

Description

[x] Modify service to add Subnets to AWS Lambda Functions
[x] Test service changes
[x] Add configurable parameter for the check
[x] Add check logic
[x] Add unit testing for the check
