[Tether09] Use INetd to call netd directly

- Using INetd to communicate with netd directly instead of using
NetworkManagementService which is a wrapper of INetd and don't have plan
to be updatable.
- Also replace InterfaceConfiguration by InterfaceController.
- Remove redundant interface flags. Only set interface up/down flag to
netd because netd only use these two flags for INetd#interfaceSetCfg.
- Note that tethering still use NetworkManagementService
to register tethering stats provider and it would also be replaced with
other way in follow up change.
