Stream Connect administrators with the kafka_namespace_admin role can view message data across different domains.

For example, in a Managed Service Provider (MSP) instance with Kafka integrations in multiple domains, managing namespace definitions properly is important to maintain separation between domains, so don't grant this role to
administrators within a single domain.
