**Expected Behavior** I want to disable to send metric CloudWatch when using spring cloud stream binder aws kinesis. **Current Behavior** (https://github.com/spring-cloud/spring-cloud-stream-binder-aws-kinesis/issues/217) **Context** I know that I can set metric config of KCL config to be NullMetricsFactory. But I cannot set that with using kinesis binder.
