Subject: [PATCH] Adds support for secure attribute on token cookie (bnc#922233)

https://bugzilla.suse.com/show_bug.cgi?id=922233  (CVE-2013-7436)
This patch adds support for the secure attribute on token
cookies (sent by nova-novncproxy). If the https is used
to transfer the cookie, the secure attribute is set thus
restricting server requestes to secure conections only.
This should prevent man-in-the-middle attacks.
