compatibility issue with request-promise: request.defaults is not supported.

[markstos]

This works with request.promise:

var rp = require('request-promise')
var r1 = rp.defaults({json:true})
var r2 = r2.defaults({ baseUrl: "http://localhost" })

But not with request-promise-retry:

var rp = require('request-promise-retry');
var rp1 = rp.defaults({json:true});
var rp2 =  rp1.defaults({ baseUrl: "http://localhost" })

The case of "double defaults" comes up with a module defines it's own defaults, but also allows you to pass in your own request object which may also have defaults. The node-strava-v3 module works like this.

It would be a welcome addition if request-promise matched the request-promise behavior here.

Thanks.
