New serverless pattern - s3-eventbridge-sns-cdk

[ghost]

Issue #1636, if available:

Description of changes:

• Adding a new Serverless pattern S3-Eventbridge-SNS using CDK.
• This pattern deploys one S3 Bucket, SNS Topic, EventBridge rule and a Lambda function which is used internally by CDK to apply configuration notifications on the bucket.
• This pattern uses AWS CDK to setup an S3 bucket that publishes events to Amazon EventBridge. When an object is uploaded to the bucket, the EventBridge is triggered and a SNS notification is sent to subscribers.
