Single Sign-On Functionality

[DarioHett]

Authentication options could be extended to incorporate functionality similar to https://github.com/brandond/requests-negotiate-sspi

Julia 1.6.0
HTTP.jl 0.9.12

The python implementation doesn't look too complicated (https://github.com/brandond/requests-negotiate-sspi/blob/master/requests_negotiate_sspi/requests_negotiate_sspi.py), but we'd need someone with windows to be able to do the work here. I could perhaps get access to a windows machine. I'm assuming the win32security library they reference is generally available on windows machines? Marking as help wanted.
