Pull request overview

This PR extends the Google Threat Intelligence (GTI) Feeds connector’s campaign orchestration to fetch and convert additional IoC-related subentities (beyond the existing campaign relationships), aligning campaign ingestion more closely with the connector’s broader relationship-fetching approach.

Changes:

• Enabled campaign subentity fetching for domains, files, urls, and ip_addresses in the campaign orchestrator.
• Updated orchestration test expectations to account for the newly fetched/converted campaign IoC relationships (as exercised by the existing stubs).
