Windows XP doesn't contain a valid CA for our cloud certificate

This is the authentication check and cloud server availability check which
are different from the one git does. The mechanism for overriding things
is different from there, but this should work just as well.

We intercept the SslErrors signal and if we get the known good hash for
our certificate, we simply call it good.
