feat(typescript): Add new CDK example demonstrating AWS CodePipeline based CICD setup for ECS-Fargate and Lambda for code sourced from Github

[nimblewish]

Describe the feature

A CDK example demonstrating AWS CodePipeline based CICD setup for ECS-Fargate and Lambda for code sourced from Github.

Use Case

Start-ups typically begin with a monolithic design running on bare-bones EC2. After a certain scale they try to move to Cloud-native solutions on AWS. Currently there is no readily available solution for this problem.
This CDK package serves as the production-grade template/boilerplate required to setup resources required to enable this smoothly.

Proposed Solution

A CDK package that serves as the production-grade template/boilerplate required to setup following resources on a high-level:

1. CICD pipeline using AWS CodePipeline
2. Lambdas (both - async triggered and rest endpoint behind API-GW)
3. ECS Fargate based service. Source code lies in a private Github repo - it is pulled, containerised using docker and image is pushed to an ECR repo. ECS Service deploys the latest built image.
4. Referencing manually created VPCs, and RDS instances
5. Secrets stored in AWS SecretManager
6. Cloudwatch Dashboards, Metrics and Alarms
7. SQS, SNS, EventBridge (MessageBus, Rules, and Targets)

The code is neatly organised into various stacks on basis of the class of services they create which makes it easy to remove whatever infrastructure isn't needed. For instance - you can comment out the stack instantiation from lib/pipeline-stage.ts.

There are six stacks -

1. VpcStack - for network infra related resources
2. DataStoresStack - for databases
3. PubSubStack - for events based infra
4. AsyncLambdasStack - async triggered lambdas
5. LambdaApisStack - lambdas as rest endpoints behind API Gateway
6. EcsFargateStack - ECS Fargate Service, Cluster, Tasks and Containers.
