Some design considerations

[iBicha]

I recently started using this library, and it's going great, loving lots of the built-in features!

But I'm also hitting some of the limitations that other libs of this kind don't face:

• The ability to "build" the request, but not send it yet
• Send the request in parallel with other requests

In short, sending a request today is doing everything in one shot: build a request, send, wait for a response.

This needs to potentially become 3 methods:

• Request() (get()/post()/etc)
• Send()
• Await()

This way, it becomes possible to send multiple requests, and control the flow of blocking the UI until a request is ready. (And by blocking the UI I don't mean blocking the UI thread, I know this lib does async behind the scenes)
