We use cookie-based stickiness for non-SSL, and we also expire the
stickiness based on the session timeout. This should make the
haproxy/horizon combo to work well, with each session sticking to one
backend, thus avoiding potential issues where requests are spread
between multiple backends.

Depends on crowbar/crowbar-ha#179

backend, thus avoiding potential issues where requests are spread
between multiple backends.

Note that we use two cookies:

 - sessionid, which identifies a session
 - csrftoken, which identifies a "login session", before a real session
   really exists, with the proper sessionid token
Since horizon is really used by browsers, the affinity based on SSL
session ID is not enough because the browsers open multiple connections.
To make sure a user always ends up on the same backend, we enforce the
balance strategy to be "source" (that is based, on the the client IP
address).
