Support modifying transport request objects before request is sent

How to access superagent’s request obj?

I need to call withCredentials() on the request obj to deal with CORS. How to do it without overriding all the methods that http-transport exports (delete, get, head, post, put)?

A good solution to this problem should permit an application author to introduce any of the following into their request chain:

• Proxy options
• Credentials / CORS configuration
• Request Logging

This may also be useful for custom authentication providers.

Workaround: Cloned the contents of http-transport.js + added defaults for superagent:

var agentDefaults = require( 'superagent-defaults' );
var agent = agentDefaults();
agent.withCredentials();

/**
 * Conditionally set basic authentication on a server request object
...

import transport from './http-transport'
const api = new WPAPI({ endpoint: 'example.com/wp-json', transport })

But… updates to lib most likely to break this anytime soon…
