Add TetheredInterface{Request, Callback} interface
Define interfaces that match the signature of the existing
EthernetManager.TetheredInterfaceRequest and TetheredInterfaceCallback
classes and make EthernetManager.TetheredInterfaceRequest and
TetheredInterfaceCallback implement/subinterface these interfaces. The
new bluetooth API could also implement these interfaces to make API surface
consistent.
Test: TH would test the existing tests that use the subclass.
