How to use the @hapi/hoek.cloneWithShallow function in @hapi/hoek

internals.implementation = function (server, options) {

    let settings = Hoek.cloneWithShallow(options, 'provider');      // Options can be reused

    // Lookup provider

    if (typeof settings.provider === 'object') {
        settings.name = settings.provider.name || 'custom';
    }
    else {
        settings.name = settings.provider;
        settings.provider = Providers[settings.provider].call(null, settings.config);
    }

    const results = Joi.validate(settings, internals.schema);
    Hoek.assert(!results.error, results.error);

    // Passed validation, use Joi converted settings
