3PH With Multiple Pipeline Steps

This is a 3PH scenario where there are pipelined calls that were made before the determination that the capability was in a third party and should be forwarded by the broker (Bob) to the final server.

The Scenario

• Vat A (Alice/Client): Our client. She wants to get a capability and immediately use it.
• Vat B (Bob/Intermediary): A service that acts as a factory or broker. It doesn't host the final capability itself.
• Vat C (Carol/Server): The service that actually owns and hosts the final resource.
