    load interface_driver using a symbolic name

    Instead of relying on a full class path let's use symbolic names and
    namespaces from setup.cfg which relies on stevedore to use a proper
    class. This can only be used for code-paths that do not rely on direct
    usage of importlib which is not the case for the metering agent, which
    is why its config is left untouched.
