CDK constructs for Kinesis Delivery stream to consume from MSK topic

Create a MSK cluster using the MskConstruct:

const cluster = new Msk.Cluster(this, 'MyCluster', {
  // configuration 
});
Create a Firehose delivery stream using the FirehoseConstruct and specify the MSK cluster as the source:

const stream = new Firehose.CfnDeliveryStream(this, 'MyStream', {
  deliveryStreamType: 'KinesisStreamAsSource',
  kinesisStreamSourceConfiguration: {
    kinesisStreamArn: cluster.kinesisStreamArn,
    roleArn: // IAM role 
  }
});

Specify the S3 destination configuration for the stream.

Add appropriate IAM permissions and roles.

Deploy the CDK app.
