kinesis: model AWS::Kinesis::StreamConsumer (L2 construct)

[humanzz]

Describe the feature

AWS::Kinesis::StreamConsumer is not covered by an L2 construct.

StreamConsumer enables enhanced fan out.

Having been waiting for cloudformation to model kinesis resource policies, to leverage that for a cross-account lambda consumer, I saw that in 2.166.0 release, that the cfn resource has been introduced, and covered by an L2 construct, and utility methods in stream but realized that StreamConsumer is unmodeled in cdk.

• https://github.com/aws/aws-cdk/issues/28814
• https://github.com/aws/aws-cdk/pull/31909

This is a request for AWS::Kinesis::StreamConsumer to be covered by an L2 construct, including resource policy utility methods and lambda event sources

Use Case

Cross-account lambda kinesis conumer with enhanced fan out

CDK Lib already has L1 construct CfnStreamConsumer. Perhaps something that could be supported at Stream L2 construct level, like exposing a method named registerConsumer().

I think a couple of things to consider

• Adding an L2 construct for consumer
• As part of that, supporting adding a resource policy, similar to the merged PR for resource policy on streams, on the new L2 construct
• consider ur suggested utility method on stream

Thing is, given how simple the StreamConsumer construct would be, am not sure that an RFC is required. @ashishdhingra If I get time to make a PR, will I be faced with saying an RFC is required?

Just an update, I'm working on a PR for this
