Add the support of PubSubHubbub protocol

[ArcticLampyrid]

Clear and concise description of the problem

PubSubHubbub (though still a working draft) is an open, simple, web-scale and decentralized pubsub protocol. In RSS channel which expects a real-time pushing, it is used to send the notification.

Suggested solution

To subscribe, the process is straightforward. Simply parse the //atom:link tag:

<feed xmlns="http://www.w3.org/2005/Atom">
   <link href="https://alampy.com/atom.xml" rel="self"/>
   <link href="https://pubsubhubbub.appspot.com/" rel="hub"/>
</feed>

Afterward, periodically send a request to register a Webhook.

Once the feed is updated, the owner will notify the hub (e.g., Google PubSubHubbub Hub), which will then forward the event to all registered Webhooks.

Most plugins for self-hosted blogs will support this, but I do not know how many users will adopt it.

Some large websites that support this feature include:

• Wordpress.com
• Medium
• and I believe there are more

This is for obtaining updates in a more timely (almost real-time) manner, of course.
