add `Subscription` to Keystone.js CMS GraphQL api

an Exmaple for Vue.js Apollo Client is also included in the /example/vue-client directory.

Usage:

Step 1:

you need to go with the custom http server mode with keystone.js. then call initSubscriptionServer with your http server and keystone object.

Example:

keystone
    .prepare({
        apps: apps,
        dev: process.env.NODE_ENV !== 'production',
    })
    .then(async ({middlewares}) => {
        await keystone.connect();
        const app = express();
        app.use(middlewares)
        const httpServer = http.createServer(app);
        
        httpServer.listen(3000, () => {
                //first step
                initSubscriptionServer(httpServer,keystone);
        })
});

Step 2:

to add Model Subscription you need to call addModelToSubscription method with your list.

Example:

const model = {
    fields: {
        name: {
            type: Text,
            isRequired: true,
        },
        //...
    },
};

const list = keystone.createList('Book', model);
//second step
addModelToSubscription({keystone, list});

Step 3:

now you can listen to subscriptions in your GraphQL api.

Example:

subscription {
    book : anyBookChange{
        id
        name
        author
        date
    }
}
