(aws-cdk): Pre / Post Synthesis and Deploy lifecycle hooks

[Dgarc359]

Description

Introduce AWS CDK Synthesis / Deploy lifecycle hooks

There already exists a lifecycle for Apps as referenced in this AWS documentation: https://docs.aws.amazon.com/cdk/latest/guide/apps.html

Lifecycle hooks would entail pre / post synthesis / deploy event hooks that would allow extensible modification of these processes.

Use Case

Being able to hook into the processes and modify the outputted Cloudformation Template with native CDK support would go a long way into modifying cdk stack deploys without intruding in a cdk app's source code.

Proposed Solution

Anything similar to other framework lifecycle hooks, but for the aws cdk synthesis / deploy lifecycle processes.
