[docs] Ajax Documentation

[dashtinejad]

I wrote a guide for making ajax requests in React, including:

• Installing 3rd party library for making Ajax request (I've used jQuery for its simplicity)
• Defining the scenario
• Creating buttons for making Ajax requests
• Sending Ajax requests
• Controlling state
• List component for showing the result
• Aborting (cancel the request)
• Error handling

There is already work in #8098, have you had a chance to look at it?

[dashtinejad]

@gaearon Yes, I've already seen it, and at first, I though how to improve it. But unfortunately, that documentation has some different concept from mine, which force me to create a new documentation, instead of editing the existing one, here are some:

• I wanted to make it as simple as possible, so I don't use any lifecycle methods.
• I wanted to use a simple (and famous) 3rd party library (for showing the way of integration)
• I wanted to show how to abort the request (using fetch in that documentation, will make it a little complex, as there is no native abort in API)
• I just wanted to show the techniques how to implement Ajax request in a React app, so I tried to avoid any other concepts, like ES6+ features (e.g. async/await).
• I wanted an interactive + simple scenario, which the user can play with it.

If you have any idea, let me know.

Thanks for the effort. I don't think we'll take a jQuery guide since jQuery isn't typically used in React apps. Most jQuery features are not very relevant in React apps so it's a disservice to users to suggest it.

I would appreciate if you could chime in here: #8098 (comment). We need a similar guide, but using axios. I think that would be the best solution and your help would be appreciated.
