Allow Kafka Topic Consumer Group to be passed dynamically in OIC integrations

Oracle Integration Cloud (OIC) currently lacks a dedicated API to update the Kafka consumer group configuration. As a result, any change to the consumer group requires direct modification of the integration itself, which necessitates granting the Developer role in production environments — a significant security and governance concern.

Current limitation: There is no API or administrative endpoint in OIC to update the Kafka consumer group outside of editing the integration directly.

Impact: To make consumer group changes, users must be granted the Developer role in production, which violates the principle of least privilege and introduces unnecessary security risk.

Requested enhancement: Provide an API (e.g., a REST endpoint or OIC console option) that allows authorized administrators to update the Kafka consumer group configuration without needing to open or modify the underlying integration.
