config: add new NMConfigData class

The NMConfig class should be immutable and its properties should
not change, with one exception: the NMConfigData property.

Later, when changing/reloading a configuration, NMConfig will only swap
the NMConfigData instance.

The NMConfigData instance itself is also immutable.
