Openconnect proxy Keep-Alive

I ran into situation, when my proxy sends "Connection: close" while trying to authenticate in spite of openconnect’s "Connection: keep-alive" request.
Openconnect first receives HTTP 407 Authentication Required for parsing available auth methods, then tries to send request with Proxy-Authorization header within closing connection and we get "Error fetching HTTPS response".

Openconnect have either to send "Proxy-Authorization" immediately, or to handle "Connection: close"

I’ve prepared small patch, which forces availability of chosen auth methods and forces authentication without detection phase.
It works for me for Basic and NTLM methods as well.

It’s a bit dirty, but usable.
