[erlang-questions] HTTP client for OAuth

[Benoit Chesneau]

Yes so there are external modules to handle the following:

- IDNA
- SSL certificates access (certifi)
- SSL Host validation
- Mimes handling (simple module providing a way to retrieves mimes headers
from a file extension and the other way)

Over the time the codebase have grown without much planning to answer to
more demands. Too much for my taste I would say. The coming version that
must land this week tends to more simplicity and less dependencies.

The way I see hackney is as a  toolbox in which you can pick what you need
to interact with the web and the web of things. It means anything to
interact with HTTP(1.1,2), Websockets and others specs like COAP once I
figured how to handle DTLS properly in Erlang.

So in short the next version is simple but will keep the current API for
the HTTP requests so going from hackney 1 to 2 shouldn't be hard.
