No support for proxy authentication

[leszekm1]

Large corporate environments often require http proxy authentication. Currently http proxy offers no support for proxy authentication.

Ideally adding something like this: https://github.com/benjimin/pywebcorp would allow automatic proxy authentication in most environments that require it. The c# SSPI wrapper can be found here: https://www.nuget.org/packages/NSspi.

I will work on this issue late this year or early next year if you don't get to it first. :)

Probably the NTLM implementation will meet your requirement?
