binder: INetwork Set/Get params interface

Add the skeletal interface for setting/getting network params. This CL
only adds the network params for non-enterprise networks.

While there,
Move the validity check for binder object to a macro that can be used
in all the binder methods.

BUG: 30251509
TEST: Will add integration tests once the implementation is complete.
