Export configuration to include signing namespace and key name
Before this change the infohub service created VP itself and just used the signer for acquiring a VP proof. With the new Signer endpoint which can create VP from raw JSON data, the complexity in the export decreased, because the infohub must not create a VP itself - VP creation and VP proofs are completely delegated to the Signer service.
Closes #3 (closed)
