Adding basic implementation of AudioNetworkAdaptor.
The basic implementation of AudioNetworkAdaptor include the introduction of
1. Controller
2. ControllerManager
ControllerManager is to hold all needed controllers. It also orders them according to their significance in dealing with current network condition.
Controller provides an interface MakeDecision, which has to be implemented by specific controllers. AudioNetworkAdaptorImpl calls MakeDecision of the controllers in the order decided by ControllerManager to collect EncoderRuntimeConfig.
