hackney doesn't work with proxies configured to accept GET (no CONNECT) requests

[brigadier]

At the moment hackney always makes CONNECT request when working through proxy. In fact, most proxies that can be found on Internet don't accept CONNECT, they work with GET only. For CONNECT they reply "403 forbidden". http://en.wikipedia.org/wiki/HTTP_tunnel - "HTTP Tunneling without using CONNECT" section.

For example 202.107.222.50:80 (not sure if it will work at the time when you read this issue though) works fine when set in browser but returns 403 when used in hackney:request. Difference in connection method can be seen in Wireshark.

It would be nice to add an option to use such proxies and have a way to specify which method should be used - CONNECT or GET.

And it is quite strange that hackney supports the same options proxy/proxy_auth as httpc without supporting Proxy-Authorization header

@qrilka not sure it's strange.... Probably just forgot that header existed. Anyway I just setup different proxy there and will try to reproduce along the day. Thanks for the feedback :)

@benoitc actually I was thinking about switching from httpc to hackney and they have quite similar API but somwhat different behaviour, and that was somewhat suprising for me.
Currently I use ibrowse for the case when httpc does not suite our needs (for the moment it's just 1 test case: httpc does not have a way to suppress retries after Retry-After being received) but we have plans to test out whether httpc isn't optimal for other usecases.

@qrilka i will add the support of such header in the week. I will add it once #78 is in place.

Thanks, but it's not a header - it's a different proxy connection method (using GET and not CONNECT) which could include Proxy-Authorization header
