    Fixed a 500 Internal Server Error when querying the quota details API
    (``GET /v2.0/quotas/{project_id}/details``) while a service plugin
    package (e.g. ``neutron-fwaas``, ``neutron-vpnaas``,
    ``networking-sfc``) is installed but its service plugin is not
    configured in ``service_plugins``. The quota engine now gracefully
    skips resources whose service plugin is not loaded instead of raising
    a ``NotImplementedError``.
