Fix Quantum v2 API method signatures
Fix Quantum v2 API method signatures

Commit d96102b6 made a change to network.api.API but rather than making
the corresponding change to network.quantumv2.api.API it appears that
it was changed to match the network manager signature instead.

Fix the quantum signatures to match the stock network API signatures.
