    Handle sparse resource registry in build_service_filter

    During image prepare, the intent of build_service_filter is to filter
    out services which are *known* to be not containerized, either because
    they are puppet services, or have been mapped to 'OS::Heat::None'.

    However if a partial resource registry is passed in, then this was
    also filtering out the services with missing resource_registry
    mappings. Since we're now assuming services are containerized by
    default, this behaviour was cause many of the issues with missing or
    no image parameters being generated.
