Transfer qubit ownership to application after E2E connection is done

[Naphann]

Currently, after connection is done (e.g. creating E2E entanglement that has high enough fidelity) QuISP doesn't do anything anymore which in the design it should send the qubit to application (Transfer the qubit ownership to the application) to do its job. When the application is done using the qubits, it should return them to the qubit pool.

Suggested Initial Implementation Allow Application to be the ownership of qubits.

1. Once the E2E connection is created send the qubits to application.
2. Application does nothing and sends it back to the resource pool.
