[IT04] Add uid as parameter of interfaceClassDataActivityChanged

Browse Source 
Add uid into interfaceClassDataActivityChanged in
INetworkManagementEventObserver. This helps the listeners to use
BaseNetworkObserver to listen for target evnets instead of using
whole INetdUnsolicitedEventListener with no-op in other event
that listeners do not care about.
