In Kiali, users can currently see the real service name and namespaces of imported services. This shouldn't happen. We have to figure out why this happens, and ideally stop it from happening. Current theory is that metadata-exchange is leaking the information.

Acceptance Criteria:

• Figure out and document why the information leaks across mesh boundaries
• (optional) No internal information is shared between meshes
• (optional) In Kiali, calls to remote meshes do not leak (real) remote namespaces or service names
